The Standley Lake Boosters purchased these ~140 colorful gators for any sport/activity to borrow for a fundraiser. We saw this at a JeffCo high school break between JV and Varsity matches. Our Ruth Willihnganz won the prize.
What you can do is charge $1 (or $2) for the opportunity to toss a gator towards the center of the court. The closest one wins a prize, perhaps $20. You could do a variation of this as your creativity allows. Certainly a volleyball or basketball match lends itself to such an easy and quick fundraiser.
These are available to borrow at the Gator Cafe. They are numbered to allow for identification if needed. Thanks to Tina DeLisa-Bosse for getting these!
