Krabs, Sandy and Squidward all leave to explore what Atlantis has to offer: Mr. There, they meet Lord Royal Highness (voiced by David Bowie), who takes them on a tour. The group sings, but Patrick "empties" the fuel by messing up the song, causing the bus to crash into a topiary garden in Atlantis. The robotic captain tells the group (with Plankton stowing away with them) to refill fuel, but he reveals the fuel for the vehicle is song (he stated that Atlanteans found the use of fossil fuels to be "counter-intuitive"). Once they put the two halves together, a flying bus arrives to take them to Atlantis. Krabs and SpongeBob convince Squidward to link the two halves together. Krabs, SpongeBob and Patrick about Atlantis. Squidward thinks SpongeBob and Patrick stole the half of the Amulet from the museum, but he soon matches it to the displayed other half of the Amulet. Krabs (who set up his own admission booth outside earlier) and Squidward (who was studying the "Neptune's Ascension" portrait before SpongeBob and Patrick ran into him). Patrick assumes the amulet belonged to SpongeBob's ancient ancestors. Then, a broken coin (half of the Atlantean Amulet) pops the bubble. It lifts SpongeBob and Patrick off the ground. He then sings a song about bubbles, then accidentally blows a larger bubble than expected. Patrick then destroys the camera for being unable to take the picture in time, but SpongeBob tells him that it is the very nature of the fragile bubble. The cartoon begins with SpongeBob blowing bubbles and Patrick taking pictures of them, but the bubbles pop before the picture can be taken. Suddenly, Encino mysteriously disappears, and Patchy tells us that this reminds him of "another lost city". The special begins with Patchy in a traffic jam, worried that he will miss the next SpongeBob episode.
