A Cocoon (まゆ) is an object which serves as a growth stage and generates an adult stage Tamagotchi. The Cocoon makes five appearances; the Tamagotchi Mothra, the Mori de Hakken! Tamagotch, the Evatchi and the games that feature the Mushitchi characters.

On Virtual Pets

Tamagotchi Mothra

The Cocoon first appeared on the Tamagotchi Mothra as a revelation from the Mothra films. 2-3 days after Mothra Larva evolves into Mothra Grub or Batora Grub, it will not evolve into an adult, but instead evolve into a Cocoon, its body connected to the Tokyo Tower. After one hour the Cocoon will evolve into an adult. This matches how in the films, Mothra hatches from her egg as a Mothra Grub, then goes into her cocoon before emerging into her adult form, although one of four possible adults will emerge from the Cocoon in the Mothra Tamagotchi which will depend on Mothra Grub or Batora Grub's Justice Meter and the quality of care given.


The last appearance of the cocoon stage thus far is on the Evatchi. An embryo will evolve into a cocoon after 24 hours, with their evolution partially predetermined based on the care it received similarly to on the Morino. After at least three hours have elapsed, the A button can be pressed to evolve the cocoon into an Angel - waiting longer periods of time will change what Angel will emerge.

In Video Games

Game de Hakken!! Tamagotchi 2

The Cocoon's next appearance was in Game de Hakken!! Tamagotchi 2. As with the Mothra Tamagotchi, it follows the teen stage and cannot be interacted with. When Chobitamatchi or Minotchi go into a cocoon, their evolutionary path will have been set and they will emerge as their adult form nine ingame hours later. The player cannot advance the clock while a Mushitchi is in its cocoon, forcing them to pass time by either taking care of a Sakanatchi or exploring the overworld.

Mori de Hakken! Tamagotch

The Cocoon later appeared on the Mori de Hakken! Tamagotch, although this time the Cocoon replaces the teen stage as opposed to following it as in the Mothra Tamagotchi and the second Game Boy game. Here, the Cocoon is named Mayutchi and is smaller as well as now resembling a peanut. Also the adult will evolve from Mayutchi after 24 hours, as opposed to one. It can also evolve into a variety of different adults as opposed to four. There is a new temperature function; there are four different Mayutchi, the one which Imotchi becomes will depend on its weight after 2-3 days. For 24 hours, the player must control the temperature of the Mayutchi. A lower temperature will yield a "colder" character such as Funkorogatchi, while a higher temperature will yield a "warmer" character, such as Koganetchi. This does not apply if the spotted egg is selected; in this case the Mayutchi will become Kabutotchi, who cannot evolve any further. In all cases however, the player should keep the temperature fairly balanced; if the temperature becomes incredibly hot or cold, the Mayutchi will die. When attempting to obtain Helmetchi, an adult will evolve into Mayutchi a second time before becoming said character.

Tamagotchi Town

Cocoons made their penultimate appearance in Tamagotchi Town. As with the second Game Boy game Mayutchi follows the teen stage, but most notably is that it is treated as a normal Tamagotchi - needing to be fed, pooping, its stress levels and migration affecting what adult it evolves into instead of Chobitamatchi or Minotchi's, unlike every other teen in the game.
