Space Penguins were aliens that resembeled penguins and could fly.
Fat Whutzat gave Lobo six space penguins so Lobo could get Mudboy for a bounty of twenty thousand credits. The space penguins were so mean to Lobo that they bit his testicles. On the way to Mudboy, two space penguins were killed due to the poor landing. After Lobo found Mudboy from the Snake, Lobo let the Snake eat the penguins.
