Dripper the sealasaurus follows the Flintstones home while his trainer is attempting to kidnap him.
The Flintstones and Rubbles go in Fred's car to the Bedrock aquarium, Oceanrock, to watch the performance- of trumpets and dance to piano music- of Dripper, a popular, trained sealasaurus, which is targeted for theft by a criminal group led by a mysterious Mrs. Big. Mrs. Big's two hires are a tall, gruff thug and a bespectacled, nevertheless poorly sighted, little oaf, and the two criminal stooges pursue Dripper after the affectionate sealasaurus befriends Barney and jumps on the back of the departing Flintstone car.
The trainer at the aquarium discovers that Dripper is missing and calls the police, and Fred and Barney first realize that they have a sealasaurus visitor when they are at home, snorkeling in their shared swimming pool. Barney's snorkel suit resembles Dripper's carcass, and the poor-visioned criminal, mistaking Barney for Dripper, throws a sack over Barney, and he and his crooked colleague bring the still-sacked Barney to Mrs. Big.
When the thieves discover that they filched the wrong article, Barney is tied to a rock pillar and left alone by the nefarious and notorious group. Fortunately, Dripper witnessed the kidnapping and followed the thugs. He provides a telephone for the tied Barney to contact police, and Dripper writes the address of the criminals' hideout for Barney to relay to the constable-on-duty. Police surround the place, Fred rescues Barney, and Mrs. Big, attempting to flee, is de-cloaked and un-wigged to reveal Dripper's trainer, who is jealous of the sealasaurus' fame and plotted the theft to remove Dripper from the limelight.

- Although Dripper is a seal not a dolphin, this episode was obviously an allusion and a spoof of the 1964 TV show, Flipper which also features an extremely intelligent and helpful aquatic mammal.
- The loudspeaker on top of the police station disappears.
