The Bubble Poppin' Boys are a group of antagonists which were a street gang from New Kelp City, and only appeared in a special episode called "WhoBob WhatPants?". Only the leader spoke, and he was voiced by Ray Liotta.
Not much is known about them, though it is known that they scared everyone in New Kelp City into never blowing bubbles. They hate bubbles because when they pop, it stings their eyes. SpongeBob SquarePants sent them out of the city by blowing a giant bubble, trapping them inside as it floated out of the town. When this happened, all of New Kelp City decided to celebrate and blow bubbles. The mayor of the city even decided to resign and give his mayoral post to SpongeBob as a reward.
The Bubble Poppin' Boys 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 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 also red, but he is considerably more muscular then the other members.
- Trevor, their leader.
- Their hairstyles, the way they dress, and the fact that they introduced themselves by snapping their fingers with tough facial expressions, is an obvious reference to West Side Story.
- The fact that they're a street gang in an obvious parody of New York City, as well as the fact that their leader is voiced by Ray Liotta, is a reference to Liotta's work in Goodfellas.
- There general apperance is very similar to the 1950s street gang greasers.
