Feed it - be sure to feed it food it likes.
Tickle it - but not too much. Move your cursor around your monster's stomach to tickle it.
Take it shopping and decorate its room.
Play games and puzzles.
Do the Daily Challenge every day.
Visit your monster every day! Take your monster for a walk and visit your friends.
