Freddi and Luther (on their way to Coral Cove Park) run into a large mob of sea creatures and the park's developer Marty Sardini, who are both angry yet terrified of this sea monster supposedly terrorizing the park. Freddi and Luther decide to investigate why this sea monster is scaring the citizens. Firstly, they get into Coral Cove Park (after getting a permission slip signed by the Mayor) and enter to find a chunk of green sea cheese with a large bite taken out of it. Freddi and Luther continue to examine it and it becomes their first clue to locate the sea monster's whereabouts.
