Meanwhile, Lucy was getting Drac ready for his 'date'. "Now,", Lucy said, who was with Frank and Murray, "Work on it.". Drac was doing a fancy type of walk, and is wearing a business suit.
"That's it!", Frank said, "You look good Drac!". "I feel great!", Dracula said, but when Lucy said that he looks fancy, Dracula soon gets second thoughts. "What? This? Please.", he said, but then Lori appeared and said, "Dress to impress, huh?".
"Impress?", Dracula said, to which he asked who. "Isn't that Captain Ericka?", Lori said, to which Dracula soon refused afterwards, but Lucy said, "That's good. Even though I know nothing about love, just go with the flow.".
"Look guys,", Drac said, "I know you are trying to help me. But...". "But what?", Lori asked. "You can't Zing twice! It's impossible!', Drac said, but then Lisa arrived. "Did somebody say 'Zing'?", she asked.
"Lisa? What're you doing here?", Lori asked, to which Lisa explained, "Please forgive me for rudely eavesdropping, but did you say you zinged twice?". "Yes, he did.", Murray said.
"Fortunately, I'm an newfound expert of Zing-ology.", she said, "AKA the study of love and zinging.". "Well that's good, but you don't understand...", Drac interrupted, "I zinged twice!". "Plus, what about Mavis and Lincoln?", Lucy said, to which Drac explains that everyone should go back home, but then...
"Hey, Dad.", Mavis said, as she was revealed to be wearing her bathing suit. Lincoln was also in his bathing suit as well, and he said, "We just came from the pool, and boy, was it crowded.".
"Having fun?", Mavis soon asked, and Lucy said, "Yes, were having fun, you know.". Lincoln was surprised, as Lucy never actually chuckled too much. "Uh, sis, are you okay?", Lincoln asked, "You look excited?". "Excited? Me?", Lucy said, "It's nothing, right Drac?".
"Yeah, we're just relaxing.", Drac said, to which Mavis said, "You know, Dad,", Mavis said, "I'm really lucky to have this time with you.", with Lincoln saying the same thing to Lucy. "All of us together, it's real special.", Lori said.
As Lincoln and Mavis decided to do the own things now, Lynn Jr and Johnny were in the sports room. "Who's up for a game of monster ball!", a monster said, and Johnny and Lynn Jr said, "We are!".
"Bring it on!", Lynn Jr said, to which Johnny said that he has played second-team coed volleyball back at Santa Cruz. "Sure, pal, whatever!", Lynn Jr said.
While Lynn Jr, Clyde, Johnny, Lincoln, Mavis, and Stella are on one team, Lucy, Dracula, Lori, Leni, Murray, and Frank are in the other. "Get ready for the spike!", Lynn Jr shouted, and she spiked the ball, to which Dracula bumped it to Leni, who setted it to Frank, who spiked it really far.
"That was good.", Lori shouted, to which Lincoln was now struggling. "Come on, Stinkoln!", Lynn Jr said, "Spike it!". Lincoln spiked the ball, and unfortunately he missed. "We won!", Dracula said with glee. "In your faces!", Frank shouted.
"Nice going, Stinkoln!", Lynn Jr said, "You made us lose!". "Now, now.", Johnny said, "It's not winning that matters, it's taking part.". "Yeah, I suppose you're right.", Lynn Jr said, "But good game though, Drac!".
Ericka and Morag, who were watching the game, just thought of a plan to get rid of Lucy, Lincoln, and Dracula. However, Ericka only wants to kill Drac, not Lucy and Lincoln. "So, how should we kill those two.", Morag said.
"I don't know,", Ericka said, "What about great-grandfather?". "Oh, he's an old coot!", Morag said, "You are the next generation, and the next generation is more powerful than the past!". "But...", Ericka said, "I don't wanna hurt two kids, even though one looks like a vampire.".
"Trust me,", Morag said, "Abraham told us we're almost at our final destination, so you can still kill Drad, while I kill the two kids.". "Captain Ericka!", Abraham said over a headset, "You're need up on deck.". "Next stop, buh-bye Dracula.", Ericka said, with Morag adding, "And hasta la vista, Lucy and Lincoln.".
Ericka decided that it would be a good idea to make everyone go scuba diving for their next activity. "Hey there, monsters! And Louds.", Ericka explained, "We reached our first destination: The underwater volcano.".
"Underwater volcanos?!", Lisa said excitingly, "I love those!". "Well then, Lisa.", Ericka commented, "Everyone grab your scuba gear and let's go see this natural wonder.". "Especially you, Count Dracula.", Ericka whispered.
"Do you see that, Lisa?", Lucy explained, to which Lisa was making observations in a notebook. "Pink glow, going around in a loop.", Lisa wrote down in her notebook.
Now in scuba suits, Dracula, Mavis, Johnny, and the Louds went down to the entrance of the scuba room. "Welcome to one of nature's most true wonders of the underwater kingdom: Volcano del Fuego.". Lisa was so amazed by the volcano, that everyone soon left her behind, but she managed to catch up.
"This is going to be a good revenge plot for me.", Morag said, and maniacally laughing before Ericka came in. "What was that?", she asked, to which Morag said, "Uh, nothing?". "Let's get rid of Dracula, remember, Dracula bad.", Ericka said.
"Forget it.", Morag said, taking over the controls, "I would kill them.", which made Ericka nervous. "But... all I wanted to kill is Dracula, not the kids.", Ericka said, but Morag wasn't listening.
"Let's just focus on that white haired brat, and his vampire sister first!", Morag said, as she fired torpedoes. As she did however, Morag missed, as Lincoln and Lucy were actually pretty good swimmers. "My turn.", Ericka said, aiming the torpedo launcher at Drac, but he dodged them too.
Johnny and Luan were together in one room, and then they saw one if the sharks, to which they joked, "Well, I guess they 'see food'.", which teased the two hunters. "What a waste of torpedoes!", Ericka said, "They reached the end already?".
"Well, if you letted me kill one of those kids first, I would let you kill Dracula!", Morag said, as they left the torpedo launcher.
"Boy, that underwater volcano sure looked hot.", Lisa said, before noticing a torpedo in the water. "That's strange.", she said, as she took pictures.
Meanwhile, Dennis, Winnie, and Lana were busy trying to get Tinkles out of the open, to which Luan soon realized what she was doing with them. "Oh, hi Bob.", Lana said, to which Dennis added, "We promised we'd go play... ping-pong now!".
"Uh, Dennis?", Mavis asked, "Who's that?". "Uh...", Luan nervously said, "It's our friend, Bob!", and Winnie said, "Say, Hi Bob!". Just like last time, Tinkles said, "Hi, Bob.", which shocked everyone. "Okay, time to play ping-pong.", Dennis said, as he, Winnie, Luan, and Lana pushed Tinkles away.
"Okay, me and Lincoln are going to get ourselves something to eat.", Mavis said, "So, bye.". Lucy soon said, "That was close,", as she was nervous that Dracula will blurt out his secret.
"Guys!", Lisa said, "You may not believe this, but look what I found swimming in the water.". She held up her phone, and it shows the picture of the torpedo. "There's something fishy about this cruise.", Lisa said. "Yeah,", Lori said, "Because it's tended by fishheads.".
In the spa, Lola was still getting her manicure. "That's good.", Lola said, "And while you're at it, can you do my pedicure too?". "Luckily, Detective Sher-Lisa Loud will figure out the truth of this cruise!", Lisa announced. "You're overreacting!", Lori screamed.
"I almost would've had them, if you haven't interfered.", Morag said, who was arguing with Ericka in the captains quarters. "You were interfering with me!", Ericka said, but Morag wasn't listening, as she asked Abraham, "How much longer until we go to Atlantis?".
"Just a few miles, I'm the one driving you know.", he said. "You don't drive a boat, you sail a boat!", Morag corrected, and Abraham said, "Whatever.". "By the way, what were you two arguing about?", he asked, and Ericka and Morag said, "Nothing!". "Good.", Abraham said, "We don't want any complications, UNTIL we get there.".
Meanwhile, Mavis and Lincoln were now in the steam room. "There's something off with my dad!", Mavis said, to which Lincoln said, "Well there's something off with Lucy.". "Really, why's that?", Mavis asked.
"I don't know.", Lincoln said, "She was more spunky, excited, and nervous.". "Really, just like my dad!", Mavis said, to which Lincoln soon asked, "Plus, why'd we have to come to this room?". "It's private.", Mavis said, and Lincoln said, "We might be holding people up though.". "You're right, let's go.", Mavis said.
As the two were getting out, they notice Lisa in a detective outfit. "Lisa, what are you doing?", Lincoln asked. "I'm on a case. Particularly, the Case of The Cruise That Went Rock Bottom.". "What are you talking about?", Mavis asked, to which Lisa reveals the photo on her phone.
"Is that what I think it is?!", Lincoln asked, to which Mavis said, "No, you're overreacting.". "Maybe we should work together,", Lisa said, "Because, I found a very important clue, which I'll tell you later.". "Okay then,", both Mavis and Lincoln said in unison.
