Though the Groomps are as funny as always, the overall animation here was a bit stiff, and the absence of a background was a bit distracting (I'll forgive the absence of a color scheme here since that seems to be the norm with Game Grumps fanimations). Since the animation is the only thing you're actually working on here, however, you simply must improve it.
All-in-all, a fun short, but lacking.
