Vanilla-Flavored Jello is a sacred treat that Chef Esteban created by special request from Uncle Hoo-Ha. It is just like normal Jello except it is vanilla flavor. It is only consumable by deities, as any mortal that eats it will die.
Uncle Hoo-Ha wanted to try vanilla Jello, but because no one has ever made it before he could not either. So he got the help of Chef Esteban to invent it. Later, Uncle Baas decided he liked it so much that he used it to create La Muerte.
