Chuchu

Chuchus, also formatted as ChuChus, are jelly-like monsters often depicted in many colors, which usually have varying properties. When defeated, Chuchus often leave a colorful glob of slime in their wake, known as Chuchu Jelly, which can be collected and used in a variety of ways, depending on the game. Similar to Bits, Bots, Zols, Gels, and Blobs, they are generally depicted as being among the weakest of Link's enemies when they appear, though they may wear armor or have elemental-based attacks.

The Legend of Zelda: Majora's Mask
In The Legend of Zelda: Majora's Mask, Chuchus are introduced as transparent, slug-like creatures with large, toothy mouths. They carry different replenishable items depending on their color. When they see Link, they will hop towards him to damage him, and can only be defeated with sharp weapons that can pop them. Blunt attacks like Goron Link's punches will simply bounce them harmlessly away. After they are defeated, they will respawn with a distinct liquid noise a few moments later. Green and red ones are found all over Termina Field and a few other places. The red ones carry Recovery Hearts (or Rupees if Link is at full health) and the green ones carry Magic Bottles. Yellow and blue ones appear later in the Great Bay Temple. Yellow ones carry arrows like the previous two carry their respective items. Blue ones only appear in one room, and carry nothing at all. Their purpose is to be frozen with the Ice Arrows to use as a platform. In The Legend of Zelda: Majora's Mask 3D, the Blue Chuchu is given a distinct blue sparkle to further differentiate it; this same sparkle is given to certain Octoroks as well.

In this game only, the Japanese version gives the colors their English names instead of Japanese names; for example, "red" and "green" instead of "aka" and "midori."

The Legend of Zelda: The Wind Waker
In The Legend of Zelda: The Wind Waker, ChuChus are now depicted as wobbly, top-heavy creatures with bulging eyes. As they move, they make a chittering noise that is actually a soundbyte of two men arguing in Japanese, but sped up and distorted. They still hop at Link to attack, but now slowly ooze after him to chase while the colors differentiate between behaviors. They can also float across water in an invincible puddle-like form, and drop Chu Jelly in different colors when defeated. Once again, red and green are the more common ones. Red ones simply pursue Link, but green ones hide from him in their puddle-like form much of the time. Both types drop their respective jelly color when defeated or hit with the Grappling Hook. If one drops an Item Ball, it will contain three of the respective sort of Chu Jelly.

Yellow ChuChus are again more rare, but are constantly electrified unless stunned, similar to Buzz Blobs. They appear most prominently in the first segment of the Tower of the Gods. They do not have their own jelly color, and as such drop either red or green jelly, with an Item Ball from one releasing a mixture of five. Blue ones are also quite rare, and are electrified like the yellow ones, but with more health. Usually, there is only one Blue ChuChu on an island, with the exception of Crescent Moon Island, which has two. They only drop their Blue Chu Jelly once each, and if enough is collected, it can be given to Doc Bandam to make the Blue Potion.

The Earth Temple and Ganon's Tower also contain a light-hating purple type called the Dark ChuChu. When attacked, it simply breaks apart and reforms immediately, though when shined with light, it becomes an inanimate statue. At this point, it can be picked up to use as a weight for switches, or thrown or attacked with the Skull Hammer to defeat it, which like the Yellow ChuChu, gives either red or green Chu Jelly. If not defeated, however, they eventually return to their normal form. Due to commonly being used for switch puzzles, they often respawn indefinitely.

The Legend of Zelda: The Minish Cap
In The Legend of Zelda: The Minish Cap, Chuchus are a commonplace enemy. Red, green, and blue Chuchus appears as they do in The Wind Waker, though the behavior of the red and green ones are switched. This is likely due to it making more thematic sense for the green ones to be in the Minish Woods, which comes before the red ones in Mount Crenel. When Link is Minish-sized, Chuchus appear as Big Chuchus. A Big Green Chuchu appears as the boss of the Deepwood Shrine, and a Big Blue Chuchu appears as the mid-boss of the Temple of Droplets. Additionally, two other types called the Spiny Chuchu and the Rock Chuchu are introduced.

The Legend of Zelda: Twilight Princess
In The Legend of Zelda: Twilight Princess, Chuchus, called Chus, appear as amoeba-like blobs that can join up together to become bigger. Their jelly can now be collected in Empty Bottles. Purple Chu Jelly is the most common, and if eaten, may either give Link a heart or damage him, with a very slight chance it will heal him more. Red and blue Chu Jelly heal more health, and yellow Chu Jelly acts as a substitute for Lantern Oil. There are also sparkling rare Chus that drop rare Chu Jelly, which temporarily powers Link up. All Chu Jelly can be sold for a fairly high price. Chus of various colors are introduced at the Great Bridge of Hylia and the Lakebed Temple, though yellow ones appear sooner in optional caverns.

In the Wii version and Twilight Princess HD, it is possible for a blue and yellow Chu to join into a green Chu in one floor of the Cave of Ordeals. The green Chu Jelly, if collected, is absolutely useless beyond being sold for a particularly high price. Its "description" in the Wii version is a blank box, while in Twilight Princess HD, it instead notes its uselessness. It likely was going to relate to a scrapped Magic Meter shown in early screenshots.

The Legend of Zelda: Phantom Hourglass
In The Legend of Zelda: Phantom Hourglass, ChuChus appear with their colors and behaviors from The Wind Waker, but lack Chu Jelly. Rock ChuChus also reappear. Normal ChuChus of all colors tend to pop out from the ground with a slight hop. Red Chuchus are the first and most basic enemy shown in the game, first appearing en masse in the northwestern portion of Mercay Island. They later appear elsewhere on the island and on several other early islands. Yellow Chuchus first appear on the Isle of Ember, and are found many times after. They can be stunned with the boomerang or even contact with Link's shield if Neri is equipped. On Goron Island, a group of yellow Chuchus on an unreachable ledge bother a young Goron, and defeating them with arrows rewards Link with a treasure map. Rock ChuChus reappear in the Temple of Wind. Green ChuChus solely appear in the Temple of Courage in this game, and cannot be hit with the sword at all unless already stunned by another item, like the Boomerang. Finally, blue ChuChus can first reappear in the maze on Goron Island or the Temple of Ice, depending on player choice. Blue ChuChus take two hits to defeat instead of just one.

The Legend of Zelda: Spirit Tracks
In The Legend of Zelda: Spirit Tracks, red and yellow ChuChus reappear with the same appearance as in Phantom Hourglass. Red ones are again the most basic enemy and are first encountered in the tunnel to the Tower, encountered after bees, Spinuts, and Keese. Yellow ones first appear in the Ocean Temple. They now move fast while electrified and hold still while vulnerable. Additionally, three new types appear. The Helmet ChuChu wears armor that can be removed with the whip, the Ice Chu Chu can freeze Link, and the silver-colored Blue ChuChu is essentially a more durable version of the Blue ChuChu in other games.

The Legend of Zelda: Skyward Sword
In The Legend of Zelda: Skyward Sword, Chuchus can merge into larger sizes, like in Twilight Princess, but have a more spherical design with a large-mouthed face. They can grab and hold onto Link. Green Chuchus appear in Skyloft at night, and have no special characteristics. Red Chuchus appear in Eldin, and are constantly on fire. As such, they burn through Wooden Shields. Yellow Chuchus appear in Lanayru in the present, and are electrically-charged. As such, their attacks hurt Link extra if he has a Metal Shield. Blue Chuchus are always found at an enormous size underwater, such as in the Ancient Cistern and the flooded Faron Woods.

The Legend of Zelda: Breath of the Wild
In The Legend of Zelda: Breath of the Wild, Chuchus are blue, rolling spheres with large eyes resembling those of their top-heavy design. They can appear in three sizes, with the larger ones having more health. They usually appear if Link is exploring an area where all enemies have already been defeated, similar to Stone Pebblits. However, there are some areas they are always scripted to spawn in unless defeated. If not pursuing Link, they may roll around or hop in place. They commonly do the latter if in an enemy encampment. When defeated, they again drop Chu Jelly, with the amount of blobs depending on their size.

Aside from the normal blue type, elemental types appear in various climates, being the Electric Chuchus, Fire Chuchus, and Ice Chuchus. Elemental Chuchus are generally dangerous to attack directly, as they will often hurt Link when he does so. However, after they lunge, their elemental "charge" goes dark and weak, allowing him to attack them without danger. When an elemental Chuchus is defeated, it will generally explode with whatever it is charged with, which can be used to Link's advantage if enemies are nearby. When they are defeated, they drop element-themed Chu Jelly, which can also be obtained by defeating a Chuchu with an elemental weapon.

Nintendo Land
Representations of Chuchus appear as enemies in the Battle Quest mode of Nintendo Land. Red ones are the simplest enemies in the game, waddling up to the player slowly and hardly ever attacking, while green ones have their hiding ability from The Wind Waker. Red ones are the first enemies encountered overall, though green ones only appear in the extra missions.

Hyrule Warriors Legends / Hyrule Warriors: Definitive Edition
In Hyrule Warriors Legends and Hyrule Warriors: Definitive Edition, Chuchus appear in red, green, and yellow in the The Wind Waker-themed bonus chapter. They can only be defeated with the Hammer, as other attacks will bounce them off. Similar to Majora's Mask, they give different items upon defeat, with red ones giving Recovery Hearts, green ones giving Magic Bottles, and yellow ones giving Force Fragments. They do not appear in Adventure Mode.

Hyrule Warriors: Age of Calamity
In Hyrule Warriors: Age of Calamity, Chuchus appear with their design and basic behavior from Breath of the Wild, most often appearing in groups and commonly as their elemental variations. In the base game, only the smallest type appears, though in the expansion pass DLC, giant-sized ones are added.
