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.
Laura – Danielle Williams, the awkward yet snarky bookworm.
Ethan – Carter Roberts, the science-obsessed boy scout.
Aaron – Dwayne Smith, the wrestling fanatic.
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.
