At the picnic, Shaggy, Scooby, and the kids were chowing on some food that the servants made for them.
Shaggy and Scooby burned up and aimed the lake, when CLST came up to them they saw a green light coming from the Harvest Moon and awoke a lot of zombies. Then they made a run for it. "It's a good thing I left my camera at the mansion," Sunny whispered. "People would think they're photoshopped."
"Same goes for our cell phones," Cho whispered back.
After the Celestian Alliance were eating up on beignets, the kid's wrist watches glew. "Zombies are scaring the kids," Joy announced.
"We need to find Shaggy, Scooby, our pets, and CLST," Layla explained to Ghetsis.
"Go on," Ghetsis replied, "but midnight will bring an end."
The Celestian Alliance didn't know what he was talking about. Felipe and Lola decided to stay here so they can get some sleep.
Outside they split up to find them. The Ghostbusters, Bryssa, Suzie, Velma, and Anne went in one direction, the Sky High 6, Alan, Fred, Daphne, and Tom went in a different direction, and Henry, Stanley, and Kevin walked to another direction.

Later Henry, Stanley, and Kevin found Shaggy, Scooby, and the kids by a bush hiding from the zombies. They decided to hide so the zombies wouldn't find them.

Meanwhile, the Ghostbusters, Bryssa, Suzie, and Anne heard something. Anne found a zombie. She tried to remove its head, but it turned out to be an actual zombie. The Ghostbusters tried to fight them off, but they were too strong.
They ran into the Sky High gang and their search party and explained everything.

At a cave, Henry, Stanley, Kevin, Shaggy, Scooby, and the kids found a chamber called the Drainomatic 7000. Kevin didn't know what they meant, and as they turned around they saw Stanley dressed as a rabbit. Sunny was thrilled and hoped they could do the bunny hop with Peter Rabbit. Lec had another suggestion that he should get rabies and scare away the zombies.
Suddenly, they heard footsteps and hid.

Back to the heroes, they found out the place was empty until Fred, Will, and Erin found a secret passageway where they found Calvino. He explained that he and the gang found zombies and hid, but they dragged everyone. But Velma, Ethan, and Tom had their suspicions when they saw a trail of logos that had a "P" on them.
When they followed Calvino, they found the Drainomatic 7000 and saw the same crest as the trail. Velma, Ethan, and Tom recognized them as the Team Plasma logo and Calvino was working for them, making Ghetsis their boss.
"Very clever, children," said Ghetsis with an evil look. "But I'm afraid you fell into my trap."
There his grunts locked them up in the Drainomatic where they saw Felipe and Lola asleep. Felipe woke up and asked if they were sleepwalking, but Bryssa and Rita told them that they were trapped.
