Role in series
"No Weenies Allowed"
He is seen standing in front of The Salty Spitoon, waiting in line. He reveals to Reg that he ate a bowl of nails for breakfast earlier in the morning without any milk, which proves him tough enough to enter the bar.
Plankton asks him and a group of other fish to be his henchmen to steal the Krabby Patty secret formula. He and the other group of fish end up stepping on Plankton, causing him to return to the Chum Bucket in a wheelchair with a cast and bandages.
