Auntie gets a Spitesucker stuck to her face when she visits Bob’s Aqua Zoo, forcing Captain Darling to make a deal with Cousin Tess to get it off. Unfortunately once she was freed, Auntie couldn't remember being sucked and was forced to try Darling and Tess for treason. Meanwhile, Russel also visits Bob’s Zoo and gets attacked by a Plurn. Gus saves Russel but the Plurn inks him, turning him into an aquatic animal. Russel goes to ask Tess how he can get Gus back to normal (leaving the finned dog with Bob and Loopy, who put him on show), but Tess refuses to help Russel until he wins her and Darling’s trial.
