Does anyone know why Superboy dislikes monkeys?

Superboy dislikes monkeys because once he was apart of the team and in the cave alone a genomorph found him and attached. He then started to hallucinate that the Joker was in the cave and that the Joker captured him. Then Martian Manhunter, the Flash, Batman, Hawkman, Superman and Wonder Woman came to the cave to find a huge present in the middle of the training room. The Flash opened it and out popped green monkeys that had jet packs on them. The monkeys attacked all of them and then Superboy found out it wasn't real because the computer didn't reconize them when they zetaed in. From all this at the end of the Young Justice comic book #2 Superboy comes to the conclusion that he hates monkeys when Miss Martian asks him if he found out anything about himself that jour when he was accueil alone. That is why Superboy hates monkeys.

It's from the comic book. Right after Superboy joined the Team, Joker attacked Mt. Justice with a box full of crazy monkeys.

Superboy probably dislike monkeys because
he thinks the geniomorphs from Cadmus
looked like monkeys.
