On many planets, mammalian life evolved from waterborne creatures slithering up on land. In contrast, the Neblitzi have, over time, abandoned dry land for the rivers and streams of their homeworld, Yzore. Their flippered legs are still pretty useless in the water, but at least they keep the Neblitz's not-too-seaworthy body upright as it bobs along from place to place like a forgotten beachball. This evolutionary quirk has not stopped the Neblitzi from developing a remarkably high level of intelligence.
