Character Actions and Analysis
Wanda is seemingly very happy to be back with the gang and on another adventure. She retains her childlike quality and she seems to accept Miss Frizzle's requests with more enthusiasm and willingness than anyone.
Wanda knows the school bus was repossessed but does not find that strange. However, her enthusiasm fades when she realizes there are no pictures of Miss Frizzle in the house that she was told is supposedly Miss Frizzle's. From then on out she is at Miss Frizzle's mercy.
At the end of the adventure, she later realizes she has been wearing the same clothes for 20 years.
