I'm purely guessing - but I think they may be talking about a version of the carnival game where the player has a rubber frog on some sort of catapult/launching device and the goal is to have the frog fly a few feet away and land on a lily pad - for which you win a prize.
I,too, would be curious about details and what materials you are using.
