The Mochi Mouse is a limited, Mythical, pet released in the Cooking Event update.

The Mochi Mouse is a small mouse with 2 stripes along its back. It can be brightly colored or pastel, with hues ranging from the entire rainbow. It appears to be carrying a small stack of mochi on its back. Depending on what variant a player receives, the left ear, body, snout, and two left legs may be a different color than the rest of it.

1. In the cooking rewards, the Mochi Mouse is listed as a Divine reward. However, when viewed in the pet stats, it is shown as Mythical. It is unknown if this is simply a bug or an inconsistency.

2. There are multiple variants of the Mochi Mouse, which is randomly selected when it is received. The icon, however, remains as the red variant regardless of the variant the player has.

3. Mochi Mouse is the third Mouse type pet added in the game after Brown Mouse and Grey Mouse.

4. It is based off of the Japanese dessert, mochi.

5. As of the Cooking Event update, the Mochi Mouse gives the most additional XP per second to a type of pet (the second being Iguanodon).

6. Mochi Mouse variants will sometimes mix up, making it look like an entirely new variant.

1. Mochi Marathon: Grants ~1.7 experience per second gain to all active Food type pets.

2. Whisker Wisdom: Every ~9:52m gains additional ~510 experience.
