- The water park was named after Wet Willie, a superhero character from The Fairly OddParents.
- It is also named after a prank attack in which the perpetrator puts their finger in their mouth and sticks it in someone's ear.
- Oddly enough Dudley and Kitty could fit the T.U.F.F. Submarine into the water park's dwellings (even though water parks have boundaries in real life).
