Two short basic moves.
All these moves use demo settings and were created using some form (however distorted) of CHEDDAR's "beginner arm decap". Also, all these moves are relaxed, meaning DO NOT PRESS C. Now that that's out of the way, here are the moves:
___mega flying jump of self decapitation:
contract both knees
space X7
contract pecs
extend both knees
press p
___short, quick self decap
contract knees
space X6
extend both knees
press p
