During the course of the episode The art of intiation, Skunk, angry at Tiger, Snake, and Fish for making fun of his age, went to the Ninja Monkey Academy for intiation with Pig. The two were informed, however, that only one of them could be intiated; the other had to wait another year for intiation. This caused conflicts between the two. They, however, both wanted to be intiated, and helped each other fight through the Ninja Monkeys guarding the academy. In the end, however, neither managed to get intiated in time. Tiger, Snake, and Fish, however, pointed out to the team that they too, had never been intiated.
Skunk: *2 sniffs*
Dr. Turtle: Skunk, what's wrong?
Skunk: I-I'm sorry! I just-just...* 4 sobs*
