Blue Shrooms are mushroom-based baddies that debuted in Papa Louie 2: When Burgers Attack!. They don't move at all which makes them not very dangerous, however they can pull their bodies inside their caps, which protect them from customers' attacks. Blue Shrooms can only be defeated when they're not inside their caps.
Hometown: Mount Monterey
Loves: Moist Ground
High atop Mount Monterey, the Shrooms start growing. Spurred by the moist, cheesy cliffs, they spread down wind into the Saucelands and beyond. Blue Shrooms are the least menacing of these mushroom baddies. Being immobile, they use their spongy, blue-dotted caps to protect them from danger. Preferring solitude, Blue Shroom’s can become rather disgruntled when visitors approach.
- For an unknown reason, the X-Zone's preview screen in Papa Louie 3 shows an image of a Blue Shroom in the background, even though they do not appear in that game. It is possible that the reason is Matt and Tony may have just reused the same animation from Papa Louie 2 but it is not know for sure.
- Their attack method may be a reference to the Mets from the Mega Man Franchise.
