Some thought… imagine there would be a fruit in form of a banana, which makes something big, or a giant model, or just some big creature. So you could feed something small, like a mouse, with it, force it to use it, and suddenly you have xyz kg of meat out of a mouse. With the right fruit by side, you could repeat that indefinitely.
