Continuity mistake: One character asks Dex to help him or he will go bald. Suddenly it cuts to Mr. Clean for the joke and he's just suddenly there. He was not in the rest of the scene or shots before that moment, and suddenly he's just there after that joke.
Suggested correction: Mr. Clean is seen multiple times throughout the scene before Hairy Hold says he'll go bald. In the establishing shot when it pans over to the group, and Hairy Hold says "Why did I agree to run the United Supermarket Defence Association", Mr. Clean is seen, albeit towards the corner of the shot slightly away from the group. He is seen more in the following shot when Dex arrives in scene. He is seen again when Maximilius starts saying "We all know when a product loses its icon...", and seen again when standing behind Hairy Hold when he says they have to find Dan. In the shots where Mr. Clean cannot be seen on-screen, he is simply just off-screen standing slightly away from the rest of the group.
