I already know that there is question like this.Its been outdated.in fact I have the link for reference.
This is kind of opinionated, but whatever.
Bunnelby, Spewpa, Swirlix, Goomy, Pumpkaboo and Bermite all look derpy (in my eyes, at least).

Scatterbug, Spewpa, Dedenne, Skiddo, Inkay, Skrelp
Are all derpy in my opinion (this is really an opinion based question :/)
