Cassie's grandparents

Cassie's grandparents are characters in Pet Shop Hop. They are the grandparents of Cassie who were responsible for running Diner Town Pets (the name of the game's setting), prior to the game's events. The shop wasn't doing so well financially, so this prompted Minerva Mink to destroy the shop in favor of making it a MegaPet shop. Cassie saw what is happening, so she decided to step in and save the shop from financial ruin.
