Whatma

From Foolswiki

Exdoom utilizes his newly gained powers to create this horrible crab/locust/frog/elephant hybrid monster, which is supposed to deal with the party while Exdoom deals with higher purposes of destruction. Whatma fails its purpose, of course, but it's probably a very hard boss battle with completely devilish music.
