Back when spro started the frog tournaments at G there were a few people that tried this because the rules were not as clearly defined as they are today.
This is true. Same for the Snag-Proof tournaments in the early days. People did some crazy chit with frogs and their other creature-frog baits.
"Flippin' deep grass."
Wait, flippin' deep grass? HTF do you do that underwater with a frog?
"We modified it."
Rules had to be rewritten. They were in the "Aw, no one would do anything like that" mode in the early days, but if it doesn't specify then someone's going to try it.
