Summary
Wubbzy catches a flutterfly and names it "Norm". He tries to give Norm a good home, but Norm isn't happy. So, Wubbzy gets Widget and Walden to help him try to make Norm feel at home. They bring him flowers, make him a waterfall, and even dress up as flutterflies, but nothing works. (In the third case, it didn't work due to the fact that Norm could tell that Wubbzy and his friends weren't real flutterflies.) Norm escapes through an open door. Wubbzy then realizes Norm is happy when he's free.
