Fictional info (?)
Suggested nameHyagyubyo
Planet typeGas giant
It has the densest atmosphere of the three gas giants, consisting mostly of methane.

The largest moon is mostly occupied by friendly yet terraformed plants known as "Bowodagi". They spend their life in lakes by consuming smaller pray. They are somewhat related to the Hachu Do but have wings and vary in length from 50 to 90 cm. They are known to endure temperatures from -80 to -40°C and to some degree ultra violet light which is common on Hyagyubyo.
