I want to see this butt-kicking karate girl blow up into a a giant cheese eating sumo, with her clothes stretched out, possibly because she is in a delicious cheese wonderland.
Gretchen enters a cheese like world and starts eating all the cheese based structures around her like a wild animal.
She gets more and more bloated from all the delicious cheesy meals she stuffs into her mouth.
The people of the cheese world decide to make Gretchen their new queen and greatest cheese eater in the world.
I took some ideas from the Puffy Ami Yumi sumo episode, The Frankie cookie addiction sequence and The land of chocolate sequence from The Simpsons. With a touch of Cheese Land from Mario Kart. Given the fact there was an episode where Gretchen really wanted some pizza real bad.
