Other mistake: The description for the forest snow house reads, "An chillin' house for two Kefkimos." Since the article a precedes an indefinite word beginning with a constant sound with the article an preceding one with a vowel sound, it should read, "A chillin' house for two Kefkimos."
Other mistake: On the title screen, there are several mistakes. First, every splash screen has the stomping hammer facing backward. Second, while the obstacles and support change based on the country/region the level the player last selected is set in, the flooring and the background are always that of a USA level. In addition, after playing a Las Vegas or London level, the sides are that of a USA level as well.
