Despite being labeled as Patchy's friend, Potty is a frequent pest, often antagonizing Patchy in the show's 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 "Christmas Who?," Potty suffers from falling to the ground twice, once pulling Potty's off-screen puppeteer down as well. Potty also breaks into two pieces after eating too much cookie dough, only to recover shortly after.
