[y-] Yoshi is [2] inside the sick ward of the [-(e)n] infirmary, taking care of the infirmary aquarium. He drops a bunch of eggs in to feed the fish, and also a 宀 dollhouse so the fish have something to play with. In return, the fish inside form the 寅 sign of the tiger as a way of wishing Yoshi good luck. In fact, the form they make is the same as this character.
