Neptune was originally thought to be made entirely of gases, but using a powerful gas mask, Grim piloted into the cloudy blue atmosphere to find a small, rocky core. This is home to the peaceful, weak, purple Neptunians. Grim saved them from the Bad-Bloogy and was elected president, and nicknamed the planet "Grim's Magical Wonderland of Awesome Junk and Awesome Gases." Not much is known about Neptune or the events happening on it. The whole thing is shrouded in mystery... and poisonous gases.
