Koopa's Mansion, London
In Central London, Koopa obtained a mansion after finding it in his cereal. Equipped with all the mod-cons and super fast broadband, he often holds parties with the other Rulers of Wiki here. He also owns a shack in Buckinghamshire which he is currently renovating.
In 2016, the house came under assault by a horde of angry squeakers, but the building suffered no damage whatsoever except getting a little bit wet from all the tears.
