how about its a worm that doesnt move its body at all when it moves (because its paralyzed, I guess)?!
EXAMPLE!!!
1. here is the worm: ~~
2. here is the worm after pressing "D": ~~ (it is going right)
do u see how none of its body parts moved when it moved??
HOLEY MOLEY THAT WAS GREAT ANIMATION
do u see what im saying!!
EDIT: nvm, this idea sounds stupid.
