Roundie

The Roundies are one of the two sapient races native to the planet Pie-Arr-Squared. Long ago, they lived in peace with the Squaries, until a Roundie named Papa Drop became leader of his species and convinced the others that the Squaries were inferior.

Biology
Like their name indicates, they're mostly spherical creatures with humanoid arms and legs. Some individuals have visible noses and some may have hair, including facial hair. Their bodies are filled with light gases, and they can be deflated and reinflated. Their primary means of locomotion are variable: small individuals float more-or-less constantly, while larger individuals can also use their legs for walking or bouncing. Filling them up with excessive gas can be dangerous, as it causes them to float up to the atmosphere without control.
