Crawly clown
The Creepy Crawley Were-Clown was a robot clown that appeared in "Tunnel of Glove." It crawled out of the wreckage of the tunnel. It scared Nancy Suzy Fish, Debbie, and SpongeBob badly.
History
SpongeBob continues to mention crawly clowns throughout "Tunnel of Glove", until, eventually, a broken clown emerges from the wreckage and begins to crawl towards SpongeBob, which yells "CRAWLY CLONW!!!" repeatedly.
Appearance
The robot's face is blue, and his body is light and dark blue. The clown has orange hair on both sides of his metal head. It has light yellow eyes and crawls on all 4 limbs. The robot has red lips and somewhat crooked teeth. He starts to crawl towards SpongeBob, Nancy, and Debbie, but apparently never reaches them because once Pearl takes the picture, he is gone.
