Moonflower

Moonflowers are a humanoid race of children-like creatures, whose main promise is to plant Treasure trees while caring for moons and protect them from an evil mysterious force of darkness known as the Big Bad.

Biology
A Moonflower is a humanoid creature; they usually comes in the form of Japanese children with different flower-like antennas on top of their heads (usually one) with a white layer that light up in colour. Moonflowers don't seem to age as they start out as seeds sent to different moons by a floating being named Little Dreamer and plant themselves in the ground. Once born, a Moonflower is given a treasure that will grow into a tree based on the exact emotions they feel.

Moonflowers seem to be able to breathe in space, as seen in Recovery.

Culture and society
Female Moonflowers are named with an ending of the word "Zuki" or "Umi" while male Moonflowers' name end with "Oshi".
