The nearest person is Vic, who looms. He's a massive centaur and looks startled at the question, equine ears pointing up.

"Uh..."

Honestly he's not familiar either, the games they play in the Centaur Pastures are only so similar due to different numbers of legs, and since past a certain age centaur colts are encouraged to be more aggressive and competitive than this kind of thing seems like. But he'll looks better if he has an answer, he knows that much, so Vic improvises with what he does know or can pick up.

"Oh, you gotta be pretty swole if you're gonna jump in a bag. And bipeds are always jealous of horses and centaurs, so they're trying to carry each other like we could carry them off, or have more legs."

Yeah. That make sense. Good job Vic.
