Much like otters, humans delight in aquatic shenanigans and look adorable eating off their own bellies. Let loose your inner otter with today’s Groupon; for $5, you get two tickets to the Waterford Oaks Waterpark's Family Fest, held on June 24 from 6 p.m. to 9 p.m. (up to a $14 value).

Amphibious families splash and slide in Oakland County Parks and Recreation's water wonderland. Stop in for Waterford Oaks' Family Fest, where overheated broods and huge, desert-dwelling sandworms can enjoy three hours of water-filled fun. Palm trees watch over the water park's tropically themed wave pool, which includes shallow-end bubblers to offer waterlogged toes a drink of air. The Big Bucket children’s playground soaks whippersnappers with waterfalls and a giant tipping pail to prepare tots for careers as Super Bowl–winning coaches, and the Ragin’ Rapids group-rafting ride plunges aquatic adventurers through a 515-foot plastic tunnel. Family Fest also douses domestic clans with a boatload of boredom-bashing extras not normally available at Waterford Oaks, including an inflatable bouncer and obstacle course, carnival-inspired games, a climbing tower, and more.
