Use Infinity Engine Editor Pro to import COCONUT.iap
Open the cheats menu in game (CTRL+TAB) and type in CreateItem:("COCONUT")...I must warn ya, though, it's an area affecting blast like Arrows of Detonation, so don't be too close to your target, or you'll be toasted along with them.....
It's Unlimited uses so have a "blast" with it and may you "always look on the bright side of life!"....hehehe...:)
