In order to join the roar omega roar, sulley must prove himself by passing the wedgie initiation something all the members went through!

Due to his jealousy over the famous scarer, Randall waits till the end of work and strike while invisible in order to prank sulley to humiliate him

Tech being dorky (and very cute, probably has some very cute sequels and moans) has received many wedgies before so he made some wedgie proof briefs and to test them out he wore them and asked slam to yank on them, the only thing is, is that he miscalculated his buddy's strength by quite a lot so the wedgie proof briefs are now just some very very very stretchy briefs

Slam fights red little guy and the little guy gets a yank on his boxers which angers slam and thus leads to a very big red guy who started to use slam as a stress toy, eventually, he finds out about his adorkable briefs underneath the boxers
