Wog

Wogs are small, non-sapient creatures native to Thiessen's Planet.

In the 21st century, they have become popular pets on Earth.

Biology
Wogs are green round amphibious creatures, about the size of a tomato, which inhabit shallow ponds of algae-rich water. They move slowly on thread-like limbs, and have large eyes.
