<P> Mavis finds out Dracula is interested in Ericka and becomes suspicious of Ericka's motives . The cruise ship reaches Atlantis which has been converted into a casino; Dracula decides to tell Mavis the truth about Ericka, but gets distracted seeing Ericka going into a crypt below the city . Drac follows her, with Mavis not far behind, and learns that Ericka is after a "family heirloom". With Dracula's help, she gets past the numerous booby traps around the object and escapes . Mavis arrives and confronts them, and Dracula confesses that he "zinged" with Ericka, to Mavis's surprise and confusion . After Ericka is told what a "zing" is, she harshly rejects Dracula's romantic feelings, leaving Dracula heartbroken . </P> <P> A regretful Ericka gives Van Helsing the object--revealed to be the Instrument of Destruction--and he proceeds to set a trap for the monsters, at a dance party . Noticing that Dracula is still upset, Mavis, after some advice from Johnny, tells her father to talk to Ericka, admitting that she was really afraid of him leaving her, which Drac allays . Suddenly, Van Helsing shows up and pushes away the DJ, and a sadden Ericka is forced to reveal, that she is his great - granddaughter . Van Helsing unveils the Instrument of Destruction, a case for a music note sheet, and plays a song that drives a friendly Kraken (Joe Jonas) that lives near the island to attack the monsters . Ericka saves Dracula from the Kraken and pleads with her great - grandfather to stop the destruction, confessing to Drac that she fell for him as well, which infuriates Van Helsing and causes him to attack them both . </P> <P> In order to pacify the Kraken, Johnny opens up a portable DJ kit, and starts playing positive songs, to beat Van Helsing's song . Upon playing the Macarena, the Kraken is relaxed and happy for good; Van Helsing is unable to counter the song as everyone begins to dance, including the music sheet (Which shreds itself to tiny pieces, in the process). Van Helsing also ends up dancing, and accidentally slips and falls but is saved by Dracula . Touched by this act of kindness, Van Helsing apologizes to the monsters and gives everyone a full refund for the cruise, before sending them back . </P> <P> Back at Hotel Transylvania, Dracula and Ericka have ended up in a romantic relationship . Drac proposes to Ericka, who stammers at the question, and she agrees to the proposal . </P>
