Kingdom Hearts 358/2 Days
According to the data Saïx provides Roxas, Shadow Globs are naturally occurring dark masses that attract Pureblood Heartless. However, they only appear in worlds where the Heartless have already infiltrated.

Twilight Town, Beast's Castle, Agrabah, Neverland, Wonderland, and Halloween Town each suffer at least one infestation of Shadow Globs during Roxas's time in the Organization. Roxas is sent to get rid of them, in order to restore the Emblem Heartless quality for heart collection.

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