Banana Peel is a crafting ingredient that was added in the June 19, 2012 Patch.
Equipping the Eliminating The Impossible set will change the Banana Peel description to "...may go on...", with random characters removed, which is a part of a quote from the "The Adventure of the Copper Beeches" short story, part of The Adventures of Sherlock Holmes collection. When combined with the other items added in the June 19, 2012 Patch, the full quote reads "Think of the deeds of hellish cruelty, the hidden wickedness which may go on, year in, year out, in such places, and none the wiser."
Two Banana Peels can be crafted to produce Error Codes; Banana Peels are not destroyed in the crafting process.
