build a submarine in order to defeat a monstrous fish living in the ducks' pond.
Eggy, Mother Duck, and her ducklings ask for SpongeBob, Jimmy, Timmy and B.O.B.’s help in getting rid of a monster in their pond, which SpongeBob, Jimmy, Timmy and B.O.B. try to accomplish by building a submarine.
Everyone except SpongeBob is afraid of the fish, so when the submarine gets stuck in an old tire, SpongeBob goes outside to untangle it and is swallowed by the giant fish in the process.
Remaining Jimmy, Timmy and B.O.B., under Jimmy’s leadership, forge ahead to avenge SpongeBob. Soon, Jimmy, Timmy and B.O.B. see that SpongeBob is alive in the mouth of the fish and toss him a bottle of soda that had been shaken up earlier when Sheen tried christening the submarine.
It causes the fish to blow up, and it is soon served as sushi by SpongeBob, Jimmy, Timmy and B.O.B..
