This weighted furball was used during the filming of the 1990 Joe Dante Gremlins sequel ‘Gremlins 2: The New Batch‘. This ball was used during the scene in the Clamp office building when Gizmo gets splashed with water and spawns 4 new Mogwai. This ball is the one that George spawns from, it is heavily weighted to be thrown and hit/drop in to the metal cabinet drawer.
