Jetpack Balloon Boy is Balloon Boy's screampunk skin released on July 8, 2021. He is Balloon Boy's third skin, after Swamp Balloon Boy and Frostbite Balloon Boy. Jetpack Balloon Boy has the same suit colors as his original counterpart, albeit slightly dirtier. Like Aeronaut Toy Freddy, Jetpack Balloon Boy wears goggles, a bronze helmet and a large coat. The goggles have an inconsistent design, with the left lens being a bright green and the right lens being blue. The right lens has been almost destroyed revealing the glowing yellow irises of Jetpack Balloon Boy's eyes. The helmet has a cyan light and a bronze gear at its center, an orange light bulb on its right and a red circular wire on its left, along with the propeller itself being a large golden gear. His coat is brown with tufts of light orange fur on its end points. He also wears a red ascot and has three belts around his chest which partially block Jetpack Balloon Boy's exposed open frame. A small clock sits on the center of Jetpack Balloon Boy's body with both the hour and minute hands turning in various directions. He also wears brown pants with purple stripes and golden clad boots. Jetpack Balloon Boy's sign says "LET'S FLY!" rather than "Balloons!". The sign is made of wood, the letters are made of silver and bronze gears reside on the front and turn occasionally. The balloon Jetpack Balloon Boy holds is made of metal. It is painted red and held together by seven different strings; one at the bottom for a person to hold and the other six pertruding off of the first and connecting to a brown curtain-like bow around the balloon. The top of the balloon is filled with steampunk gears, lights and other machinery. Jetpack Balloon Boy's gray metal jetpack is strapped to his back and has twin boosters tanked with gas, allowing him to take flight several feet into the air.
