The Minions Mike and Ken are busy at work in the mailroom. Ken, bored, decides to throw a box of expired PX-41 samples into its designated chute. The box explodes, which mutates Mike to some extent. The infected Minion mutates back forth between his normal body and his PX-41 enhanced body. This leads to trouble when three kittens end up in a box headed towards the mailroom. Ken manages to keep the kittens out of Mike's hands. Mike sneezes out the PX-41 out of his bloodstream, but the mutagen lands on the kittens, perhaps spelling certain doom for Mike and Ken.
