<P> Rising slightly, one of the final discoveries made is the ruins of Atlantis, along with a typical Disney - fied sea serpent, accompanying mermaids, and a treasury bursting with jewels and gold . With the ruins of the ancient civilization soon left behind, the Nautilus would enter the final phase of its journey, with a tribute to the most iconic and memorable part of the 1954 Disney film: The attack of the giant squid . After seeing a much smaller sister Nautilus trapped in the clutches of one such creature (Curiously marked XIII on the tailfin), the passenger submarine would be attacked itself by long, thrashing tentacles . </P> <P> With a final push to the surface, the Nautilus would clear the caverns of the dangerous squid, and enter the safety of the tropical lagoon, on its way towards the dock . </P> <P> Though the attraction was a guest favorite and remained popular throughout its existence, it was expensive to maintain, as well as having a low hourly loading capacity for an attraction of its size and expense . It was closed on September 5, 1994, without advance notice, for what was outwardly termed a temporary maintenance period, but in 1996 the closure was officially made permanent . </P> <P> Post-closure, several vehicles were left stationary in the lagoon and by the dock, before the entire fleet was eventually pulled from the attraction in 1996 . The submarines were regularly moved around to different locations in Walt Disney World backstage for several years, until eventually being stripped and buried in a landfill in 2004 . Three of the vehicles were saved from the fleet's demise . Two were shipped to be sunk in the snorkelling lagoon at Castaway Cay, Disney's private island . Here, the two submarines were placed in various areas of the snorkelling lagoon and covered with cargo netting to help sealife and microbial corrosion cling to them . As of 2008, only one of those two Nautilus submarines still exists, but both its wheelhouse and dorsal fin have been destroyed by hurricane weather . The third submarine sits in a lot behind Disney's Hollywood Studios . It can be seen in the "bone - yard" section of the Backlot Tours next to some props from Star Wars or Pirates of the Caribbean . The submarine is in a fair condition, with no damage visible to those who pass by . </P>
