My name is The B.O.B....and I too....am a closet-worms fan...
I used to play that game everyday with my brothers...who says you need souped up graphics to have fun...all it takes is something strange and new to enjoy...as for the drawing, it is almost on par with the actual worm sprite, but he does looks a lil evil than the normal characters. Also, ditto to what Irate Corpse said, cuz that is how they actually move...But I still think it's cool that someone here finally drew something worms...the series deserves more credit than it has...good job
On a side note, in real life, worms pull themselves forword using tiny, unseeable hairs. So for all you know that's what he was thinking when he made this. So you're both wrong, it goes with the normalcy of physics, and if a worm really wanted to, he probably could walk with his head up like that. No point though, as they would 'walk' slower and couldn't see as well. Either way it matches the style they use in the game and is physically possible.
God I'm a nerd.
