Planet Arispade

Planet Arispade (惑星アリスペード) is the third planet that the crew of the Astra visits on their trip back home.

Principles
It is almost completely covered in water, and the few islands on it are subject to frequent flooding due to massive planet-wide tsunamis that occur when earthquakes strike. It does, however, have a vast array of marine life in the ocean and birds on the islands.

Trivia

 * Arispade is an anagram for the word "paradise".
 * Arispade is inhabited by animals that reproduce by cloning. This is likely foreshadowing about the real reason Group B-5 were sent to McPa.
