Pop's Mop Top Tots is a family barber shop that is owned by Pop. So far, it only appeared in Carbon Copies where Dudley and Kitty tries to get The President to give him a haircut. But if he doesn't want a haircut, he'll eventually destroy Petropolis. After The President gets a haircut, he'll stop destroying the city. But the family barber shop turns out to be a holographic area thanks to Dudley and Kitty.
