The gang beats up the people of New Kelp City whenever they blow bubbles. They were flown away in a giant bubble by SpongeBob.
They all have black pompadour haircuts, black leather jackets with their logo on the back, jeans, and black boots. Their leader has orange scales and can make a claw grow out of his pinky finger.
Three of the other Bubble Poppin' Boys have similar appearances, yet one has green scales, one has purple, and one has red. Another member of the gang is a yellowish-beige color and he is considerably more muscular than the other members.
They scared everyone in New Kelp City into never blowing bubbles. They hated bubbles since whenever they popped, it would sting their eyes. Whenever people break their rules, they beat them up for it, and the town never blows bubbles out of fear of the gang coming.
