While I didn't care for them much when I initially watched RiD'15 with Underbite's character not really jumping out at me, I had a quite sudden urge to draw more, looking back I found Underbite was a "Chompazoid" and just knew I'd end up drawing more.

Look at this adorable little Chompazoid puppy! So young yet so hungry for metal!

God I just think I really love Chompazoids, they're so cute! I even got a screenshot showing Underbite has peets/paw pads! Aaaaa so cute!

So yeah, in short I've come to like Underbite slightly more and love Chompazoids.
Yesssssss.
