Note : The Raccoon is an item that was meant to be added in AG&D by Dodge Roll but unfortunately never saw the light of day.
Apache Thunder managed to fix up the original code left in the game files and created his own modified behavior for the Raccoon that causes its effect to trigger on dropping junk. He also allowed me to use his code to make this item.
I decided to add the junk chance on room clear as an additional benefit that helps pay for its primary effect.
