The Gubru discovered the Okukoo on a bright, light, pampa-covered planet 35 000 years ago. On their homeworld, flocks of millions of these leaf-eaters blotted out the sun when passing overhead, yet Okukoo would never completely defoliate an area.

Looks like a "vertical hummingbird" with four wings equilaterally set around the torso. Ten dark eyes are spaced below a four-jawed beak. Tentacles han below the torso for manipulation. They are known to lift several times their own weight. They seam eager and polite and lack any sense of humour.

Mainly works as agile messengers and engineers for their Gubru masters.
