About
🧡💜 Monster City: Where Every Day is a Festival 💜🧡

Monster City
🧡 A city with a fairy-tale worldview 🖤 Western-style streetscapes 🧡 Purple skies, pink clouds, pink moon 🖤 Buildings are primarily black-themed 🧡 Cute bats and ghosts fly about
Residents of Monster City
💜 Absolutely no malice 🖤 They love pranks, but only small, cute ones 💜 "Excessive pranking" is not festive = not fun 🖤 Since the motto is "Fun for everyone," it's surprisingly safe 💜 Generally broad-minded; they don't get mad when pranked (since they do it too)
