Answer :
Answer:
Not necessarily.
Explanation:
The texture of an animal's skin isn't necessarily going to help it fly. Flight consists of aerodynamics and assests like wings, a fanned tail, and/or a pointed figure, like a bird possesses. Adding this slime/goo that you mentioned will not add to it's aerodynamics, meaning that the answer would be no.
If you give the animal a lighter frame as in bones then they would be lighter and fly easier.
