Mudy Crystal is the second boss from Darius Force. It is shaped after a Portuguese man-o-war.
Mudy Crystal will be constantly swinging a tentacle to protect itself. while this tentacle can be destroyed, it regenerates after a while. His only attack is to release floating mines which explode into a three-bullet spread. After the shield protecting his head is destroyed, he will stop with the mines and start shooting energy blasts at the player.
Both versions of Mudy Crystal have the same attack pattern with the only difference between them being the different palette.
