This is Professor Garbanzo's Fix-It Shop.

This is where Proffy keeps her tools and materials. In its chambers she keeps raw materials from the Four Realities, gunk'l'dunk, tools, healing blanktanks, and various other things that might come in handy some day. The remains of Der Kveen are stored here.

The leaf-like structures on the top are actually insignia, like those sported by Mr. Teach'm.

The Fix-It Shop and Professor Garbanzo have a relationshop that outlasts the Beanworld's season. Apparently, they are partners each year. Without the help of the Fix-It Shop, Proffy would never have found the Four Realities. This story is recounted in issue 21, The First Time Professor Garbanzo Discovered the Four Realities.

The Beans hid in here once when they thought Gran'Ma'Pa was mad at them.
