People call Decidueye and Incineroar fursuits all the time, but what's weird is that I've seen WAY more Decidueye fursuits than I have Incineroar ones (most of which are just Mimikyu-tier stitched-together fabric sheets rather than actual fursuits) despite the latter's body fitting the mold better - you know, no weird arm feather things.
Also I'm pretty sure felines are more popular with furfags than birds.
