The only downside I can see is retaining my human sentience. Be that the case, life would be an even harder struggle, to hunt food everyday and try to not get eaten alive by predators.
Wouldn't you be a super smart for a frog? I'd find a place that's sturdy with a bunch of spiders to mouch off of and maybe befriend a dog, honestly frog life homesteading could be pretty sweet
I think I'd like to be an elephant. They're very smart and social, they don't have to chase after their food, and they're too big for anything to eat. As a human who appreciates animals though, frogs are still my favorite.
