SizeChange - Book of Spells

Casey and Emma find a magical spellbook at their house. Their classmate, Mariono, comes over to work on a project. They use a shrinking spell on him and he shrink down. Then then tease him about his tiny size and everytime they tease him, he shrinks even smaller. They continue to tease him about liking their giant feet and he becomes micro-sized. Casey then uses a growth spell on herself. She teases Mariono a final time and then crushes him with her foot.
