Vegas, baby! As the grandparents spend the day counting cards, the kids get dropped off at Sucrose Park, a guardian-free amusement park. It's all fun and games until everyone's favorite "rat"-ical mascot makes an appearance. THE PLAYERS: Laura – Danielle Williams, the awkward yet snarky bookworm. Ethan – Carter Roberts, the science-obsessed boy scout. Aaron – Dwayne Smith, the wrestling fanatic. THE MONSTERS: Jack Jack – a purple-furred blink dog. Swiss Army – a giant Swiss Army knife with a Chicago accent. Sir Spins-A-Lot – a top hat wearing giant spider.
