Evoglobin

Evoglobins appear in the Rump Command part inside Bowser's body in the game, Mario & Luigi: Bowser's Inside Story. They are purple with spiraling, ribbon-like arms. When Mario and Luigi explore there after Bowser has been knocked unconcious by his castle, the Evoglobins plead with the plumbers to go through the area and revive Bowser, telling that they are a part of Bowser's soul. They are larger than normal Emoglobins, however, Mario or Luigi do not need to jump on them to active their message.

If Bowser is not in peril and the Mario Bros. decide to visit the Rump Command anyways, they will appear as regular Emoglobins colored purple, and will be silent if the Marios jump on them.
