He was first seen coming out of the circus-tent spaceship with Rudy, then made a balloon pooch to hunt down Mike and Debbie, but he and Rudy were knocked down when Mike drove backwards, hitting them with his car.
Spikey was then entertaining a man with a puppet show. The show was that a male was wanting to kiss a female who didn't want him to, so she took out a gun and killed him. When the audience laughed, Spikey stood up and took out his cotton candy gun to trap the unfortunate soul inside a cotton candy cocoon, then laughed evilly. When the Terenzi Brothers were driving around looking for the Killer Klowns, they spotted the Parade Klowns and Spikey was with them.
Spikey and Bibbo were the first ones to realize that Mike, Debbie and Officer Hansen are in their circus tent space ship, then the three humans ran to the elevator with Bibbo and Spikey knocking on the doors. Spikey was seen trying to catch Mike and Debbie and Officer Hansen when they infilitrated the Big Top, but was unsuccessful when he was blocked by a closed door. He chased the three everywhere they went along with a few other Klowns. Officer Hansen only managed to shoot one of their pursuers, Fatso. Spikey then came in trying to kill the three humans, who were trapped standing on a stack of giant blocks, until the Terenzi Brothers came in and petrified the Klowns with orders from the fake clown head of Jojo. Spikey was last seen leaving when Klownzilla had come and looked twice to see that his real leader was arriving.
Spikey briefly appears in the music video for the song Killer Klowns From Outer Space by the Dickies, when the band is replaced by Klowns, Spikey is the drummer.
