NIL is in charge of the class mascot for the weekend, and takes him on an outing to the park.
He's a beautiful little clownfish that everyone loves. But Bip, on the other hand, sees him as a
scary monster who's invaded our world and so he cooks up a serious and infallible plan to get
rid of him. The kids have to put a stop to that and bring Bip to his senses.
