"Pretty slow today.... guess everyones at the show.
But of course Sans is still here."
Good world design elements that you should almost always use:
Large carnivorous monsters that kill and eat people but also serve as mounts and are sweet babies with the people that handle them.
Floating islands that logically make no sense but are cool to explore
Baseball bats as weaponry in any remotely modern-ish setting
Elemental type triangles/squares
Nonhuman cultures and locations build with their individual bodies and abilities in mind
