Doom-shroom is Jalapeno's best friend. Like all mushrooms he sleeps during the day, but with a Coffee Bean he can wake up. Also "seen" in Issue 3 as a burnt sillhouette, which his best friend, Jalapeno, burnt a whole lunch line.
Talking to Jalapeno in Issue 4 and get burned by Jalapeno again.
Amount of times being burn: 2.
