My 7 year-old daughter is trying to play a PlayStation copy of Gex. She has successfully fought her way to the first boss level....but cannot complete the level. The level is called "Spin and Puke". She can handle the "spin" part (whacking some skulls with the tail) but is at a loss at how to handle the "puke" part. Can anyone help?

I've been unable to find a walk-through for Gex. If someone can point to one, that would help as well.

Thank you in advance!!
