Muffin stumbles on Samuel and Rudy's playhouse, but they won't let her come in. She stomps away and Quinn helps her build her own playhouse, even better than theirs. When Samuel and Rudy ask to visit, Muffin won't let them. Mr Beakman suggests they stop quarrelling and put the playhouses together. They take his advice and make the best playhouse ever.

Muffin comes upon a strange plant that she affectionately names Pee-Ew. Pee-Ew smells so terrible that no-one wants the little plant in the tree. Muffin helps the community realise that they can't cast out this peculiar plant just because of its smell. The community works together to make a home for Pee-Ew on 3rd and Bird.
