Mark is despondent as he has not just lost his new pet, Marco Polo, but his old pet Ben. Frank from Seaquarium takes Mark and Tom out on a boat to find Ben and Marco Polo.

After Mark has a series of mishaps that soil three pairs of Tom's pants, Tom is angry at him. Feeling unwanted, Mark moves in to Ben's shed. While fishing, a fisherman comes by the river and hires Mark as his guide. The small boat overturns at a rough spot in the river and Mark and Mr. Carter are threatened by alligators and a cougar.
