Despite being labeled as Patchy's friend, Potty is a frequent pest to Patchy, often antagonizing him in his live-action segments, although they usually make up by the end of the episode. For instance, in "Shanghaied", Potty shoots Patchy out of a cannon. In "Friend or Foe", Patchy and Potty get into a fight that temporarily ends their friendship, which Patchy compares to how Plankton and Mr. Krabs became enemies.
Potty is often comedically damaged and/or destroyed on multiple occasions, always making an offscreen recovery between shots. For instance, in just his first appearance, he suffers from having his strings cut, making him fall to the ground, then having Patchy pull his strings down, pulling the puppeteer down with him, and finally, his body breaking apart from his head after eating too much cookie dough.
