Long ago on Gaus there was a fearsome predator with tough, leathery skin, that was armor-plated and yellowish in color. Because it’s color pattern resembled that of a Banana, it was given the name Bananasauros.
The origin of Banasauros is uncertain but fossilized remains have been found in the warmer regions of Gaus where remains of fossilized plants (some of them bore a strong resemblance to your modern day Cavendish Banana trees) grew. Fossilized eggs have also been found in a few scattered caves in the tropics and neo-tropical areas of ancient Gaus. It is hypothesized that the yellow skin was the result of a genetic mutation that worked in its favor.
