Cosmic Crash

Sam, the old trumpet, is once again not there but hanging around in the garden of the research lab when an unknown flying object crash-lands in (!) the poor boy. The death was witnessed by a concerned colleague, whose body now serves as a vehicle for the angry blob, which embeds itself in the onlooker's head and takes control. With his puppet under his alien butt, he can enter the laboratory unhindered. But what the hell is he actually doing there?
