Okay, so it's implied when Tom asks what your favorite animal is, that's what you turn into. What if it's an amoeba or some really primitive predator, like a jellyfish?
- No answer for the jellyfish, but it's explicitly stated that crossing turns you into an animal, and amoebas are protozoa, not animals.
- What if your favorite animal was an insect or arachnid? There haven't been any arthropod villagers thus far, so are there even Gyroids for those? Also what would happen with your limbs if you said your favorite animal was a snake...?
In the bad ending why didn't the government arrive since Nook had already tipped them off.
