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, brought him back to life by fusing the villain with his manor as a giant monster. However, Sora, Donald, Goofy, and Jack Skellington managed to put him down for good by destroying the Shadow Globs that were animating him. Unlike in Days, they are capable of casting Fire against you when near them.

Kingdom Hearts 358/2 Days
During a mission in Twilight Town you have to destroy seven of these Shadow Globs. They're totally harmless on their own, but usually attract many Pureblood Heartless, such as Shadows.

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.
