"The Majestic Spunge is a master at illusions and pranks, the former of which may be the cause of its unorthodox appearance. Pranksters from every corner of the monster world come every year to consult the Majestic Spunge and learn of its grand ideas for pranks, despite the fact that many pranksters simply want a small-scale laugh that they can do before lunch. Majestic Spunges are infamously bioluminescent, and work well as nightlights. They don't like standing still for too long, but, hey, you need to find some way to keep them out of trouble."
Credit to all.
