|Season 4, Episode 21|
A Thanksgiving Carol
Jake fears that Adam wants to leave the school.
- The plot of this episode is a parody on The Brady Bunch episode "Dear Libby", where the kids find a newspaper complaint, from an anonymous writer, who can't stand taking care of his/her six kids. The kids fear this was written by their parents, so they try their darndest to improve their behavior. In the end, it was learned that the true author was someone completely different. Similarly, in this episode, Jake reads a news article called "Dear Glibby", about a kid going to an all-animal school, that he hates.
- Third on-screen appearance of Jake's Parents, (excluding the cameo of Jake's mom in "Animal School Musical").
- The same zoo goers from "Meet the Spidermonkeys" return in this episode.
- Final appearance of Chad.
