foogoolian fungi forest

On the planet foogoolia there isn't much in the way of diversity - all animal life is limited to the foogoos and crabs of various shapes and sizes. All plant life consists of bioluminescant fungi due to the planet's stale atmosphere and near-nonexistant day/night cycle.
Here we see a typical adult foogoo chasing down some prey; a donut shaped crab, which can roll at speeds upwards of 90mph, but is totally fucked in the absence of a downward slope.
