You brew a potion out of it with a banana, cucumber, slime, and a horse dildo. If you want more recipes you can buy them at 800 Where you get the free fat potion. The banana and cucumber seeds can be bought at a separate shop, the horse dildo is at a shop next where you get the free fat potion from. And to get slime you kill slimes, I bought an explosive staff for that. I do not know how to make it unless it's possible to make it. And before you ask, they explosive staff is where you get the horse dildo.
