Shadow Glob

The Shadow Glob is a Pureblood Heartless that is found in Kingdom Hearts and Kingdom Hearts 358/2 Days. It is an immobile, black-violet orb of darkness. While it does appear in Kingdom Hearts, it is unnamed, and is only given a name and journal entry in Kingdom Hearts 358/2 Days.

Kingdom Hearts
After Oogie Boogie is defeated, his darkness, in the form of Shadow Globs, brings him back to life by fusing the villain with his manor as a giant monster. However, Sora, Donald, Goofy, and Jack Skellington manage to put him down for good by destroying the Shadow Globs that were animating him. Unlike in Kingdom Hearts 358/2 Days, they are capable of casting Fire against you when near them.

Design
As simple as they come, Shadow Globs are semi-spherical, tumorous, black blobs with an inner purple glow. When hit, they wobble much like gelatin.
