'''Treacherous Halls''' is a promotional [[e-Reader]] level for ''[[Super Mario Advance 4: Super Mario Bros. 3]]''. Its official difficulty rating is ★★★★★, making it one of the more difficult e-Reader levels. Much of the level consists of [[stomp]]ing enemies over [[spike Trap|spikes]] to cross them. Many [[Piranha Plant]]s also appear, as well as two [[Flurry|Flurries]], one of which has to be ridden to collect an [[Advance Coin]] and also a [[1-Up Mushroom]]. [[Boom Boom]] is fought at the end of the level. It was initially released only in Japan, but it eventually became available internationally when the game was brought to the [[Wii U]] [[Virtual Console]] in 2016. The key art for the card featured Boom Boom.
