Fish

Chibi-Robo! Plug Into Adventure!

You can find the fish in the kitchen. Chibi-Robo can feed them any cookie crumbs he finds in the house. You receive more Happy Points and Moolah per cookie crumb than you do for throwing them in the Trash Can. Each fish will give 8 Happy Points and 8 Moolah when fed (while crumbs will give 1 Happy Point and 5 Moolah at a Trash Can), but fish should only be fed once per day/night cycle, otherwise the subsequent feeding will yield the same Happy Point and Moolah as a Trash Can. The game starts with 1 fish in the tank. By feeding these fish, they will eventually grow to 6.

In this game, there are fish in a tank in the sushi bar. They are different from the fish in the first game. In Exploration mode, you can interact with them by tapping their tank. Once you do, some fish will get scared, and swim somewhere else.
