Larry's Chillton Hotel

Larry's Chillton Hotel, labeled Larry's Cave Hotel on its entrance, was a hotel found in Hotel Mario, owned by Larry Koopa. It was actually an ice cave which replaced doors with refrigerators and featured other ice themes. Enemies found in here were Koopa Troopas, Monty Moles, Spinies, and Buzzy Beetles. Once this hotel was beaten, its interior exploded; Mario and Luigi barely managed to escape this explosion and Princess Toadstool had the even less fortunate fate of being carried away to Lemmy's High-ate Regency Hotel, where the Mario Bros. traveled next.

 * The Chillton Hotel is a pun on the word "chill" and the Hilton brand of hotels.
