I only have one thing to say about We All Scream for Ice Cream, WOW!
The way this episode started reminded me of something out of a Stephen King Book or Movie. An evil Ice-cream man abducting children by hipnotizing them with a tune and trapping them in his van.
That's what I thought in the beginning but when Prue & Pheobe saved the children from the cold park dimention in the van it turns out that they are evil demon children.
Prue & Pheobe with the help of Piper & thier dad, who is back in town, set off to right thier wrong and get the demon children back into the ice-cream truck.
The children were great actors & actually freaked me out a bit.
Out of all 8 seasons, the third is the best.
