Quite possibly the geekiest toy we've ever featured on this site – Star Trek Interactive Tribbles.
What's a Tribble you ask? Well, if you've ever seen the original 1960s Star trek episode 'The Trouble With Tribbles', you'll know exactly what they are. For the uninitiated, the Tribble is a cute furry creature that squeaks and has the power to calm down the average human. But there's a drawback – they multiply constantly, so your average spaceship will be full of them in days.
These battery-powered replicas don't multiply, but they do squeak and shake like the originals when 'disturbed', with a beneficial effect on your nerves likely too. They come in two sizes (small and large) and various colours, with prices starting at $14.99 (around £9.25). If you want to see them in the original TV show, see over the page for a clip.
