it might be nothing special to you but i pulled it off so i'm happy...ok first off

do not hold
space x 6
then hold all
extend ankles knees and hips
raise shoulders
contract pecs
*grabby hands*
space x 3
extend hips
contract knees and ankels
space x 2
lower shoulders
and if you want you can hit space and jump out at the end or w/e...
for some reason it turns out different every time even if u use the exact same controls...once i managed a flip over his head ripping his arms off and headbutting his head off...go figure

That's a nice little grab you have there.
