Mickey and Pluto go fishing. Pluto has a run-in with a clam, who eventually lodges in Pluto's mouth; Mickey thinks the clam is Pluto's tongue and can't understand why Pluto keeps begging for more food. After they get rid of the clam, Mickey's attempts to use his minnows as bait are thwarted by a hungry seagull; he brings his friends, and they chase our heroes away.
The Simple Things
While Mickey fishes at the beach, Pluto has bad encounters with a clam and then a seagull that also steals Mickey's bait and fish. The pair are eventually chased away by all the gull's friends.
