Well, it's somewhere! I know because I'm the one who first discovered it. Also, I made a mistake. The peel is bigger, but somehow when you resurrect it it's a normal size banana.
Yep. It's already somewhere in this thread, but I don't blame you for not digging through 20 pages. It also works on a peel from a holy banana, but you'll just get a banana of a different size.
When we had a development discussion during IVANcon, the idea was brought up and Kahvi explicitly stated that it was something that was planned, but not implemented. Therefore, I am not sure that the weapon info attached to it is something that is actually in-game, or just planned.
