Bloop

Bloop is the twenty-third episode of Season 1, and the twenty-third episode overall.

Synopsis
"The Nektons are trying to identify a unique life form. They've never seen it, they've only heard its sound: 'Bloop'. Just as Ant discovers its true nature, a huge underwater mining machine threatens to destroy it!"

Trivia

 * Deep sea-mining machines have been developed but have yet to see any use due to deep sea-mining still being a new concept in real life.
