Marlin decides they he and Dory should swim over the trench to find the East Australian Current. During their swim, they encounter a school of jellyfish. The jellyfish sting does not bother Marlin; however, he knows that Dory could get hurt from the stings. Marlin makes a game of bouncing on the tops of the jellyfish to keep Dory out of their tentacles.
When Marlin and Dory realize they are lost, Marlin starts to panic. Dory suggests they ask a whale for directions. After they receive no response from the whale while speaking English, Dory attempts to speak the whale's language.
Dory drops the scubadiving goggles that she and Marlin found, and they swim to the abyss to find them. In the darkness, they find a light emitted from an anglerfish, which attempts to prey on them. Marlin distracts the anglerfish and directs its light to the goggles so that Dory can read the address on them.
