The Munsters' travel to Marineland to find Eddie a new aquatic pet, arriving in style in The Coach, where they garner the attention of the veritable ringleader of this maritime so-named 'carnival', which is really just being entertained by a group of minstrels playing classic tunes of Americana {including "This land is our land"*}, watching Bubbles and the killer whale show, along with a gaggle of acrobatic water clowns performing diving tricks in costumes with various props.
Marilyn and Eddie remain in the stands watching the show. At one point Herman deposits a fish into one of the resident mereswine's gullet.
But the show is delayed due to the gentleman not being able to place the park flag way up on the flagpole, which Grandpa obliges through teleportation, demonstrating his own acrobatics while up there.
As far as acquiring a new pet is concerned, I recommend a manta ray, the veritable bats of the sea, or "aquabat", to match the mammalian Igor. An octopus is considered, which would also be a fine choice {just ask Pugsley}, or piranha {which make for great leftover disposal like The Addams'}, or perhaps an eel as Grandpa suggested. A shark is considered too expensive upkeep, and would be better suited there at the ocean. Fortunately, there's always Spot!
This Marineland excursion special marks a 71st "lost episode" found.
