Snake in the Grass

A snake\worm game that seems to be using two sounds from Anders Bjerin's freeware game SYS (1989): the smacking of lips whenever you eat a white mushroom and the "Yehaa!" when you pick up bonus mushrooms. While the smacking of lips is always sped-up, the "Yehaa!" is either sped-up or slowed-down, depending on what bonus you pick up. It was created by Peter Harris with these assets and released to public domain in 1993.
