Originally, Momo, or my main persona, was/is a string monster. That’s still true for the most part, though it’s more of a silly name that doesn’t have too much meaning behind it. All in all, they are just a fluffy little critter that has a weirdly bare face.
If I were to actually assign some sort of species, they would be a strange offshoot from a sphinx. Their face isn’t human, but it’s not exactly animal either.
