Planet Woooo is a spooky planet. Think of Pumpkin Hill from Sonic Adventure 2, Twilight Town from Paper Mario the Thousand Year Door, or Forever Forest from Paper Mario. It always appears to be night since the planet is covered in a dark mist. Only moonlight shines through for some reason. It’s probably magic or something. Most of the planet generally has fall or winter-like weather and climates, so it’s cool or cold and leaves barely stay on trees.

The inhabitants include Boohoo(s) (pronounced buu-huu[s]), Punkin(s), Lamphy/Lamphies, and Fungeists (pronounced fun-gaist[s]).

Boohoos are ghost like and have ghostly tails. Sometimes have cold, fiery hair. The youth enjoy pranks and playing spooky tricks on visitors to their planet.  Notable ones are Boonny and Phant.

Punkins are pumpkin-ghost aliens. They’re basically like Boohoos, save for being pumpkins. Their eyes glow in the dark. The only notable Punkin is Gilly.

Lamphies rule the water of Planet Woooo. They’re fish creatures who live in the dark waters of the planet. Luckily, they’re born with lights attached to their heads. They’re amphibious, so they can also survive on land. The only notable one is Cayenne.

Fungeists are mushroom like creatures. They’re generally shy and will scream or expel spores that can cause temporary paralysis if startled. They’re both kept as pets and are wild too.
