[18/02] Have you ever attempted to come up with reasons as to how a Pokémon can use attacks (e.g. how a Pokémon can breathe fire)? Why/Why not?

Yes, I hate when the only reason I can come up for something in a story is just "because."But, some things just really can't be explained. Certain attacks (Iron Tail and Explosion, for example) just seem to stretch the limits of my belief.
