RUBI FLEA – Itchus smarticus

Gnasher’s Fleas – Rubi Flea

Rubi Flea loves to know how things work and needs to try to make them work better. She's always deeply immersed in experiments and theories, and constantly dreams about understanding the secrets of the gnashiverse via the appliance of science.  

Despite the fact the Rubi Flea is smaller than a microchip, she instinctively knows how any electronic gadget works. No-one know how but some people believe that it's simply from being on Gnasher's back and overhearing Rubi von Screwtop, a human who shares part of this bug's name.

Apart from scientific experiments, your adopted flea enjoys all sorts of other activities, like watching documentaries about science and listening to podcasts about her heroes Albert Einstein and Marie Curie.

The Rubi Flea's favourite colour, as you've probably guessed, is red, and will bring lots of joy into your home. Particularly if you love science as much as they do.
