Evelyn

Evelyn Evelyn (pronounced "Evil-lyn) by Willa) has been out to get Willa ever since Tiny the elephant stepped on her lunch box. She hates the fact that Willa is always so upbeat and nice to everyone.

Willa tries her darnedest to avoid Evelyn, until her nemesis crosses the line and starts making fun of Willa's animals. That does it! No way is Willa inviting Evelyn to play "moonbounce" on Bert the bear's belly. so there.
