imagine it, you've fallen asleep with your typhlosion, he's laid atop you, keeping you warm...
the gurgling in his stomach wakes you, and you look up to see his bottom end facing you- and he's effectively got you pinned down.
it seems like it would be nothing to think of, and a return to sleep is in order, closing your eyes until the sounds are heard again, in greater intensity. opening back up to look, and a brown nugget has begone to work it's way out of his anus, slowly inching out on a trajectory straight on to your face, with nothing you can do about it- typhlosion is too heavy of a sleeper to wake up, pinned down as you are, so all you can do is lay there as he slowly releases his feces onto your face.
