Wild-World Beach should be the perfect place for a day of fun, but a frightening sea creature has other ideas. Join Scooby-Doo, Shaggy, Fred, Velma, and Daphne as they investigate what is disturbing the shore. Choose which trail the gang follows, whether they stay together, and when their search needs a break for snacks. Each decision takes the maritime mystery in a different direction, with a new chance to uncover the truth behind the monster.
