Based on the Spongebob episode Arrgh.

On one sunny day, Granny Smith is bored out of her mind hoping for something exciting to happen and then she got we wish when Spike and Gabby are playing a pirate board game to find a hidden treasure chest. She seems to like it when she start playing it, perhaps too much and even got Spike and Gabby to go treasure hunting with her for real without even question if the search is real or not.
