The gang beats up the people of New Kelp City whenever they blew 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 blow bubbles out of fear of the gang coming.

Their hairstyles, the way they dress, and the fact that they introduced themselves by snapping their fingers with tough facial expressions, are obvious references to West Side Story. They are also similar to the T Birds from Grease.
The fact that they are a street gang in an obvious parody of New York City, as well as the fact that their leader is voiced by Ray Liotta, are references to Liotta's work in Goodfellas.
The Bubble Poppin' Boys are a parody of the Burger Palace Boys in the original musical film Grease.
