When standing on top of a Blue Jumper, we know it jumps a little lower. But you can fix that.
It is possible, at the height of the jump, to both jump off of the Blue Jumper's head, and pick it up, simultaneously! This allows you to take it with you in your new jump, and at the height of that, throw it down and jump even higher!
I did this by mistake and bumped my head on a ceiling I didn't even know I could hit
I wonder if there is a way to keep doing this and get extream heights...
