MapleStory/Towns/Aquarium

Aqua Road, is an underwater-type area. The way players navigate differs from the norm, and there is also an HP-reducing feature similar to El Nath. Air bubbles purchased from the shops in Town and dropped by monsters can negate this loss for 15 minutes at a time. Also, by doing a quest for Hughes in Orbis Tower B2, one can acquire an Air Tank that allows for breathing in Aqua Road permanently when equipped. Aquarium is the town of Aqua Road. Aqua Road is currently available in every version except EuropeMS.
 * Aqua Road

Aqua Road is accessible from the 2nd basement floor of Orbis Tower.

Players may jump to swim upwards. The monsters there are generally harder to defeat, due to the strange gravity system. The weaker monsters in the shallows are rarely hunted, mostly due to the fact that better training alternatives exist in areas closer to Victoria, and it is difficult for lower leveled characters to make it all the way down. At the far left, a hole in the Orbis Tower allows players to exit, and if one continues walking to the right, he will reach Aquarium. There is an NPC called the Dolphin Taxi, which can take players to the furthest map, The Sharp Unknown, for one ticket. In this area, a story book similar to the one in Helios Tower's Library, is located, which will take the player to Korean Folk Town.

There are hidden streets near the outskirts of Aquarium to teleport you to the Aqua Road Dungeon. The monsters there range from level 80 to 110. At the bottom of Aqua Dungeon is a map where the giant fish boss Pianus is located. Pianus is considered one of the "Big Three" bosses. It is very difficult to defeat, only just behind Zakum. Pianus is not hunted as often, however, because it has inferior drops, as well as attacks capable of killing most archers and thieves in one hit. Also, unlike other bosses such as Crimson Balrog, Papulatus, and Zakum, a player killed in this map loses the full 5-10%, the same as they would anywhere else, as opposed to the usual 1% lost by death to bosses.
