Can't beat that stupid giant snake...

What am I doing wrong? I lured him away so he'd activate the floor panel that lets me jump up and get the part, then I leap down and try to use the part underneath the blue crystals and I get nothin'. I see a tractor beam and it starts to pull me up but it looks like that Halloween Simpsons where the aliens have trouble suckin' Homer up in the tractor beam. It struggles for a second then shuts off and I fall to the ground. This game is annoying. Any suggestions?

It seems that a lot of ppl. have trouble here, hehe. Go to the beam, when it appears, simply hit the up arrow. That will take you up to where you should be, . Then go walk onto one of the panels up there to kill the snake. You'll need to time it right though.
