A colourful species of slug-like aliens.

They prefer living in warm, humid locations, and have very little tolerance towards cold.

The balloosks are somewhat timid and scare easily, when frightened, they gulp air to inflate and appear larger, their bodies stretching like rubber to assume their ballooned up form.

Some however have been known to gulp air and inflate for fun.

Balloosks are genderless, and they reproduce asexually

Feel free to make your own, but credit me at least.
