K-9 Unit is a group of worms that work for the Bikini Bottom Police. They appear in the episode "Slide Whistle Stooges."


They are green K-9 worms. They have silver collars with spikes on them and are very vicious. They look like other worms in the series, such as JK.

Role in episode

When the police sergeant calls for backup to get rid of the slide whistling from SpongeBob, Patrick, and Squidward, the K-9 Unit shows up in a SWAT van. But Squidward then plays his slide whistle and the worms start acting up. They then attack the K-9 Handler, who yells at them. Beaten up, the handler yells out about how he was supposed to retire that week.
