I vaguely remember this. I saw it back in the 90’s on TV. I remember there was a teenage girl who went to a birthday party or something and was blindfolded. They were all playing a game and the other girls put a frog in that girl’s mouth. She spat it out. Later she was seen out of that house crawling on the grass and gagging I think? Later on the movie this slim woman gives her an apple or some other type of fruit from a tree. The girl bites into it and there’s a worm.
