Push and throw the enemy off the platform. Don't fall!
Ok so essentially when the game starts let the players fall without moving then when blues arm hits oranges head, make blue grab. Then have blue hang off the edge with their arm on the ledge (all still holding orange/not getting closer to orange so that the arm is grabbing the head at the highest grab range). Try to have the edge where the arm comes out of blues body but doesn't touch it be right on the top right corner of the platform. Occasionally this will stretch the arm automatically but if not... Then perform pause buffering. Basically repeatedly press the left arrow key and "a" when its paused. doing this for long enough while stretch the arm out. Repeat if it doesn't work first try.
Things to note
*If blue flings upwards this isn't good. You want blue to sorta slam his body into the side of the platform in order to do this.
*This glitch is very hard to perform if you don't really know what your doing. I figured this setup after running into this glitch sorta on accident and worked on this setup for like a month afterwards (then again this was to discover it so pulling it off will prolly be shorter).
