Niceland Apartment is a custom set created by Npgcole based on the building from the Disney movie Wreck-it Ralph.
"Wreck it with Ralph and fix it with Felix! Wreck-it Ralph is wrecking the Nicelander's apartment and only Fix-it Felix can save them, thanks to his golden magic hammer! Can Felix save the day, or is it game over? It's up to you!"
In Litwak's Arcade's video game "Fix-it Felix Jr.", Wreck-it Ralph wrecks an apartment in Niceland, and the citizens depend on Fix-it Felix to repair the damage he has done by tapping broken windows with his magic hammer which fixes everything it touches. Ralph is supposed to be the game's villain, but he would much rather be a hero.
