This pokemon has a random nature and preferences. To guess his needs, use your instinct. However, if he is really hungry or bored a lot, he will let you know. He may gain too much weight if you feed him too much, but he will lose weight if he plays. If you don't take care of him, he'll die eventually. Don't let that happen! There are two kinds of food (the worm and the fly, the fly is more perennial) and two kinds of games (the plume and the ball) because he may not like one of the two (he may that he doesn't like anything. In this case, click again on the green flag).
