After being fed by Miss Fire the original blob was attacked by ? but the blobby creature was merely cut into many pieces that then continued to harass the arena. Finally Miss Fire shot a popcorn tin out of the arena and the blobs chased it, searching for food. Eventually the popcorn tin and the blobs found their way into space and Antestarr's Secret Warehouse in an asteroid where he killed them all with a gigantic salt-shaker.

The leftovers were leftover food found within the chest mini-fridge of Galvatron, the robot. They'd been there so long the leftovers had grown sentience. He tossed them aside and them were almost killed by Miss Fire[NeS1 2]. She then, instead, fed the leftovers a hot dog. At which point they grew overly excitable[NeS1 1].
