Chak-chak

The chak-chak were small, six-limbed rodents that were popular pets on their homeworld, the planet Chad. Their two arms were long and deceptively strong, folding away beneath their long fur, and they moved at great speed on the four smaller legs. Shortly before the Clone Wars, the Chad-based company Rebaxan Columni created the MSE-4, MSE-5, and MSE-6 series repair droids all inspired by the chak-chak. Although most potential customers were unconvinced by the prospect of owning a mechanical rat, the Galactic Empire eventually bought the company's entire remaining stock of MSE-6s.
