Following the rule of emperor Upshe Daisy, the streets of Marushal had long since been swept free of crime by the militia. However one public nuisance still lurked on the streets: vermin! Rats and stray cats and dogs.
Enter professor Hiro Hatsushiba, he created the ultimate animal killer... BLENDETHRA a machine made from a lawnmower, a vacuum cleaner (with extra hoses) and a blender. Blendethra was a success, the streets were becoming free of small animals which normally tipped rubbish bins over and shat everywhere; suddenly the poor things were running for their lives, before being blended to a bloody pulp.
Unfortunately, one day Hiro's precious pet parakeet was tragically killed by Blendethra when the professor was out receiving an award for services to the community. The killing machine was shut down for good, or so the professor thought. For you see the professor had made a grave mistake by using a laptop computer as a basis for the machine's artificial intelligence, ...it still had battery power and the means to charge itself. One day the professor noticed that Blendethra had vanished. Suspecting theft, Professor Hiro called the authorities but the machine was never found.
If you have a pet or perhaps a small child, you might want to keep them in sight. There are those who believe Blendethra is still out there...
