|“||This little bulb glows with the love of a pure heart, but no one wants to get anywhere near him. It's tough to make friends when you electrocute anyone who touches you. Still, he keeps on glowing, 'cause that's what you do.”|

Bzztbulb appears to be a white lightbulb-like creature that has a yellow lips and beady black eyes. He has a yellow ring around his body and three feet.
Bzztbulb acts similarly to Sparky; he periodically projects an electric field around himself. Unlike Sparky, however, Bzztbulb stands idly in one spot. Gondola Bzztbulb, a variant of Bzztbulb, is the same enemy riding in a gondola. He attacks by sending electrical currents through the track that gondolas ride across.
Bzztbulb's name is derived from a portmanteau of bzzt, the English onomatopeoia for static electricity, and lightbulb, referencing the enemy's appearance.
