HOLLOW EARTH

Expand your mind and your creativity with this wildly imaginative adult coloring book.

Explore the maze of caverns, ancient insectoid temples, spooky reptilian swamps, juicy alien jungles, and forgotten cryptid cities that exist beneath our feet. You will bring these alien worlds to life as you color them in, with the pages progressing deeper underground as you go. If you're not careful, you may not find your way out again. Ghostshrimp is an illustrator most known for his work on Adventure Time for Cartoon Network, The Midnight Gospel on Netflix, and more.
