There is a Super Nintendo game that is also known by the same name, Tiny Toon Adventures: Wacky Sports Challenge.
In Wacky Sports Challenge, you choose to play as either Buster Bunny or Babs Bunny and participate in your choice of sports activities, including baseball, soccer, or even tennis (but of course, with a toony twist.) As Buster, you can also play carnival games that characters like Shirley the Loon and Fifi Le Fume have set up, like a watergun gallery and beat the clock challenge featuring Elmyra Duff.
