Katelyn, the goth girl, tricked the mail lady into coming inside her house. She thought she was going to get some lemonade but Katelyn shrinks her instead! Katelyn's absolutely fed up with the mail lady meddling with her mail and to get revenge she crushes the mail lady as a little tiny rodent (please note the rodent is a prop. It is fake.). Her transformation device made the rodent extra durable. Katelyn wanted to make sure she could crush the mail lady over and over and over to teach her a lesson! When Katelyn's done having fun with her, she tosses her remains into the trash.
