So far, there have never been two of the same level type in succession (apart from Flattering Heights and Mount Evernest).
I’m surprised enough that Hamberg is a Cobalt Plateaus-themed world, since I was thinking of it as a pun on Hamburg like you. And other big cities (like Stockholm as Steakholm) were Pig City-themed as well.
Oklahoma is not a city name but the name of a whole US state. I would’ve said Flattering Heights but now Hamberg took its place… call me crazy but I’ll say Bamboo Forest for Oinklahoma.
