 The still-inverted goldfish bowl knocked off the ledge by Doc Sturgeon in the previous episode sinks down to surround Goldie the Goldfish as she swims from the entrance to the reef pocket in which she had tucked herself. Baron Barracuda finds himself unable to get to her through the glass. He tells Trigger Fish that they should depart, but declares to Goldie that they will be back. Doc, Finley Haddock, and Georgie Porgy swim to Goldie, and decide that she will be temporarily safe therein. All three depart to get Miss Minerva, again leaving Goldie unguarded. The Baron and Trigger return, then swim to the ledge, to push a rock from it, with the intention of breaking the bowl. As Finley, Doc, and Georgie travel to get Miss Minerva, they see Diver Dan descending, and conclude that he is a monster. However, after a pause, they concern themselves with the more pressing business of retrieving the Mermaid. As the Baron and Trigger struggle with little success to push the rock, Trigger spots the approaching Diver Dan, and directs the attention of the Baron to him. At Trigger s suggestion, the two flee. Finley s party reaches Miss Minerva. They tell her that there is trouble both from the Baron and from a monster. When the ostensible monster is described to her, she identifies it as a surface man in a diving suit; she says that things will be fine so long as they keep some distance from him. When Goldie is described to her, Minerva identifies the goldfish as such. When told that the Baron is already after the goldfish, Minerva tells the party to show her where the fish is.
