When Pe'ape'a the giant bat kept knocking and scratching the door open, the heroes exclaimed as Cathernia ran towards the door, and pressed the door close to hold the bat from coming in.

Cathernia: How do you know this is Calvin's?

Drac: (nervously) Well, uh, Ericka and I have kind of been researching him on our own. A little. I mean, we just searched Van Helsing's forbidden library, meant to take the cruise here in Hawaii, searched for a thing called "Cobra-porcupine"… Okay. You know, hearing it out loud, it comes off way worse than it sounded in my brain. Ericak has nothing to do with this. It's my idea.

Cathernia: How could you keep this from me? From Leo? From Agatha?

Drac: I was trying to protect you from a potentially devastating revelation.

Cathernia: (angrily) Or you just kept it to yourself so you can feel special. Classic Dracula! He's my great-great-great-grandson and Aggie's great-great-grandfather!

Drac: (guiltily) Okay, it's just first I didn't tell you because I didn't want you to get hurt. Then I couldn't tell you because I found out all this stuff and I didn't want you to hurt me. I'm sorry, okay?

Cathernia: (in rage) You're only sorry 'cause you got caught!

Drac didn't feel guilty for what Cathernia said. He tried to ignore it, until he noticed Aggie on the corner. Everyone turned to Aggie on the corner, who held a blue jacket of her ancestor, and shed tears from each eye. She felt sad that she knew nothing more of her family history, and her friend kept it from her.

Ericka: Aggie, are you okay?

Aggie: You kept a secret about Grandpa Calvin. My great-great-grandfather. (she sniffs and wipes her tears) That is not okay.

Now Drac and Ericka felt guilty. They realized they shouldn't have kept information about Calvin from everyone. In fact, Cathernia, Leo, and Aggie are Calvin's only direct family, and they have the right to know about their family history, no matter what it is.

Just then, Pe'ape'a successful broke the door down. Everyone shrieked as they tried to get away from the giant bat when it started to attack them. The I team doesn't have weapons with them. Because of the term "vacation", they don't need weapons to spend the rest of the Summer and they left their weapons back on the ship. They all quickly ran out of the tomb, and split up, separating from each other.

Even Dracula was separated from his family, friends, and Ericka as he kept running, not only for his life, but to find his love ones.

Drac: Mavis! Ericka! Guys! Where are you?! I should have told all of you! I'm sorry! I need your help!

Dracula noticed the bat was after him. He used his telekinesis to make a pile of rocks to slow the bat down, but it still flew over them. Drac accidentally tripped on coffins and tombs along the way as some blue smoke came out of its place.

Drac transformed into a bat to fly over a huge pile of rocks ahead of him. He then transformed back to his original form and hoped the rocks blocked that giant bat's way, but it still flew over them. Drac slowly backed away and covered his eyes and face when the bat attacked him. But nothing happened and heard familiar voices in front of him.

Numbuh 4: Scram!

Wendy: Shoo! Shoo!

Timmy Turner: Back up! Back up, you bad dog!

Ton: Not food! We're not food!

The I team and the monsters threw small rocks and sticks at the giant bat.

Drac: (surprised) You came back!

Frank: We're friends and family, buddy!

Mavis: Good or bad, whatever we do, we do it together!

When the giant the bat was about to strike again, our heroes gather up, ready to fight the bat together. Unbeknownst to them, behind them were blue smokes come out from the ground with white glowing eyes. The blue smokes took form of a dozen different kinds of monsters and few humans. They were the ghosts of the deceased close friends and family of the Drac, Frank, Murray, Wayne, Griffin, Eliodoro, and Cathernia, One of the ghosts was actually Martha

When the giant bat charged at the I team and the monsters, they and the ghosts roared at the bat like crazy before it attacked them. The bat stopped as it was frightened by the ghosts behind the heroes, and it flew away in fear.

Aggie: Friends and family victorious!

King Julien: It worked?!

Johnny: It worked!

Dennis: We gotta start doin' that all the time!

The monsters and the I team didn't get a glimpse of the ghosts who helped them behind them. The ghosts were just happy to help their friends, family, and other new friends.

Mavis was the only one who noticed the ghosts behind her. She also noticed the ghost of her mother, who was beside Dracula. Mavis saw how happy her mom was, even her dad held Ericka's hand. Martha didn't show any signs of anger or jealousy. She only smiled at him. She was so happy that her husband finally found someone who can take care of him when she was not around with him anymore. The way she noticed her mother's smile, Mavis just realized Martha was so happy for Drac, and will always love and support him with his new life him, no matter what. If her mom is happy, her dad is happy, Mavis is also happy.

Later, they all returned to Van Helsing's "tomb", where Aggie and Cathernia unpacked Calvin's things from the bag. They found his jacket, clothes, a water bottle, and goggles.

Just then, Hank noticed another pair of goggles from the bag.

Hank: Van Helsing's goggles! That must be the borrowed golden mask from the riddle!

Pedro: So Calvin Galido took his goggles, hid it, and the elaborate riddles in the catacombs and the deadly bat spirit were…

Aggie: Were all just an elaborate prank on Van Helsing?

They all looked at the goggles on more time, and when they realized it was just a prank, they all laughed at Calvin's dangerous mischief at Van Helsing, because of the former being younger than the latter.

After the laugh, Drac and Ericka looked at the others with guilt.

Drac: We should have told you from the beginning. Good or bad, we're all in this together. (To Cathernia and Aggie) Aunt Cathernia, Agafya, I should have told you two. Calvin was your family… your relative. You have the right to know about him.

They all smiled as they accepted the apology.

Ericka: (holds the note) Well, I guess we're all starting from scratch.

Aggie: Wait. Did you rub a pencil over this?

Ericka: (confused) Huh?

Aggie: (takes the note and a pencil from her hair) Have I taught you nothing? Fireside girl Article 2, Section Stacy, Footnote 14: Rub all documents with a pencil.

When Aggie shaded the back of the note, it revealed the concept or blueprint of the cubical machine with a green and purple circular swirl on the front, and stakes, torches, knives, guns, and other dangerous weapons, which are weaknesses of all kinds of monsters, were attached to together. The name of the machine was also revealed.

Ericka: (gasps) The Cobra-porcupine! Now we know what it looks like!

Griffin: Is that a date circled?

Drac: "March 1893". Guys, this is the month a met Calvin!

Eliodoro: What does that mean?

Cathernia: We'll find out together.
