Bosko the hot dog vendor is at the beach pushing his cart as his weenies dance and play. An octopus and some seahorses dance by the shore, then join together to form a merry-go-round, which some scallops hop out of their shells to ride. Bosko's dog Bruno gets a nail stuck in his paw. Bosko pulls the nail out, and Bruno thanks him with a big lick in the face. Elsewhere Honey and Wilber are skipping along the shore, but Wilber gets swept off his feet by the waves over and over again. Honey starts to play her ukulele but stops when her kitten Wilber runs near the water. Wilber dips his toes into a puddle, but huge waves keep scaring him away.
Bosko is still pushing his cart when he spots Honey. Honey tells him to wait as she is going to change in a wooden changing room. She changes out of her bathing suit and into her regular skirt. She and Bosko go to a picnic and start singing a song. The song is interrupted by Bruno's barking. Bosko tries to get rid of him by throwing a stick for Bruno to fetch. They keep singing until Bruno comes back, with a bigger stick. Bosko throws that but Bruno returns with a log, and Bosko throws that too. Bruno comes back this time with a huge tree, which he drops right on the picnic blanket, flipping a jar of jam up into the air and down onto Bosko's head.
Wilber, still playing in the puddle, gets washed out to sea and calls out for help. Bosko hears him and jumps into the water, but the surf retreats and Bosko finds himself on dry land. Bosko jumps in again, performing what he calls a gravity-defying swim, but the waves keep pushing the two apart. In a last ditch effort, Bruno ties an electric fan to his tail, hops on a log, and floats out into the water. He turns on the fan and uses it as a propeller and saves Bosko and Wilber.
