You may have thought combining Transformers were something else, but wait till you see combining Scraplets! That's right - the scourge of Transformer-kind, the robot consuming micro-bots known as Scraplets, have another trick up their collective sleeve. Not only can Scraplets eat away at a robot's metal skin, but - as Goldbug and the Throttlebots are about to find out - they can also combine with each other fo form one giant Scraplet! Can even the miracle cure the Transformers have discovered (water, to us) defeat the Scraplets? And can it save the rapidly disintegrating Blaster, when saving him will also save the three of the Autobots' deadliest enemies - the Decepticon Triple-changers, Astrotrain, Blitzwing and Octane? It suspiciously looks like a no-win situation for Goldbug and the Throttlebots. Because, if they fail to destroy the Scraplets, Ratbat - the Decepticons' fuel auditor - will take steps to wipe out Earth altogether!
