Thorn Shrooms are one of the three types of mushroom enemies in Papa Louie 2: When Burgers Attack!.
Thorn Shroom is a large, prickly Shroom that grows abundantly in the muggy marshes of the Saucelands. It has evolved a menacing cap of sharp, blue thorns to ward off any annoying creature from jumping on its head. Being firmly planted in BBQ sauce, Thorn Shroom prefers growing in large groups. This can be rather problematic for passers by, as a large briar of Thorn Shrooms can easily block an unkempt path.
Thorn Shroom has an off-white stem and a white cap with dark blue spots and caps. It is larger than a Blue Shroom
Thorn Shrooms are fixed in place and do not walk around. They regularly rise to expose their stems, then drop down so only their spiky cap is exposed. When only their caps are exposed, they are impervious to attacks from players.
