Here you can see Toby the Octopus in his favorite napping spot over the Deck tavern.

Inspired by the Puerto Princesa subterranean river I created this world where the pirates would be troglodytes and have their lairs inside stone cliffs! Everything would be a little ranky and rough because well, the humidity could eat the wood up really fast.
