Woo! Looks like Deku Aen discovered his ability, another way to "fatkiss" people! The Deku Inflatoxin bubble. So strong, it cannot be easily penetrated (and can be detonated at will, releasing all the inflatoxins inside, fattening whoever is in the range. But he still doesn't know that, soooo.....)
Here, he's just having a fun time with bubbles and magic, not knowing these bubbles are inserting themselves into a Noivern's mouth on the way, accumulating in his body and swelling him up like a helium balloon! Good thing these bubbles haven't been detonated. Yet.

Commission for PsychoFloatzel on FA with his Custom Noivern pokemon!!

Deku scrubs and Pokemon belong to nintendo!
