The duo make their way through the cave, avoiding ghost pirates while searching for ladders to venture deeper into the caverns, where they find the missing half of the Atlantean Amulet.

After repairing the bus and arriving at Atlantis, the group is greeted by the Lord Royal Highness (or LRH).

He plans to use the Atlantean weapons, the most advanced of all time, to destroy SpongeBob and his friends and take over the world.

While taking pictures of attractions (dealing with tourists and Atlantean guards blocking the way), Patrick accidentally destroys the oldest living bubble.

The group make a run for it, in which they must evade Atlantean forces while searching for paper clips to unlock doors.

LRH captures Plankton, believing he is a talking speck, and displays him as both a replacement for the recently destroyed bubble and the national treasure of Atlantis.

Squidward, on the other hand, uses the tentacles on his feet to run across moving carpets and on treadmills to break open doors or a portcullis.

[1] On GameRankings, the PlayStation 2, Wii, Nintendo DS, and Game Boy Advance versions of Atlantis SquarePantis hold ratings of 60%,[4] 62%,[5] 66%,[2] and 72%,[3] respectively.

Likewise, the most-criticized aspects of all versions were the clunky camera control, the lackluster AI, and the annoying method of having to return to the start of the level to switch characters.

[6] An IGN review of the Wii version called the game "second-rate", "sloppy", "tedious", and "really boring".

[8] The PlayStation 2 version was criticized for the same reasons but was given a slightly lower rating, because IGN wrote that Wiimote controls spice up the shooting games.
