You probably couldn't delete it if there was already a reply to it.
I do the same thing as Bunnie. I try to knock out the baddie, grab the ball (or racket), get all the scribbles and then go to the door (you get more points then taking each scribble to the door by itself). And then, once I have them all, I go up as high as I can and wait for the bonus things to fall. On most levels the baddies can't jump up that high, so I don't have to worry about them getting me. Plus you get quite a bit of time, so you can wait for a while and get lots of stuff. An added bonus is the things don't disappear right away, so you don't have to hurry go get them. Once the time gets close to running out, I find out where the baddie is (hit him if I need to), jump down and get to the door.
I'm glad you finally beat the game though!
