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 to either of Oakland County's water parks. Choose between the following options:

• For $8, you get admission to Red Oaks Waterpark (up to a $16 value), opening for the season on May 28.

• For $7, you get admission to Waterford Oaks Waterpark (up to a $15 value), opening for the season on June 10.

Amphibious families splash and slide about in both of Oakland County Parks & Recreation's award-winning water wonderlands. Float effortlessly down Red Oaks Waterpark's 990-foot-long River Ride on provided inner tubes. The balmy, 78-degree Terrific Tides wave-action pool rocks and rollicks, and the three-flume Triple Turn sprays a trio of spirals pool-wards. Water jets, curtains, and a 6-foot tipping bucket drench wee waders at the Soak Station, and the zero-depth Spray & Play area lets toddlers souse in safety, much like a pickle in an arm floaty.

Palm trees watch over Waterford Oaks Waterpark'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 tadpoles with waterfalls and a giant tipping pail, and the Ragin’ Rapids group rafting ride plunges aquatic adventurers through a 515-foot plastic wormhole.
