Sugie was sleeping peacefully until she was awoken by a loud beep. Thinking it was 4am, she looked outside to see a van. But upon closer inspection, Sugie realized it was the Mystery Machine. "Wake up!" she exclaimed. "Zoinks!" Shaggy said, startled. "Hi bro," Sugie said with a smile. Scooby, still half-asleep, asked, "Where are we?" "Come on Scoob, we're home," Shaggy said. Sugie smiled, picking up Scrappy, and said, "Aww, isn't that cute?" She then noticed some mail that had arrived. "What?" Shaggy asked. "Your old friends," Sugie said.
Shaggy and Scooby were surprised when they heard Suge's voice calling them from the kitchen. When they got there, Suge handed Shaggy a letter from Fred, Daphne, and Velma. In the letter, they apologized for the way they had treated Shaggy, Scooby, and Scrappy in the past. They expressed their regret for not noticing how hurt Shaggy and Scooby were, and for splitting up the group and giving Fred all the girls. They asked for forgiveness, but said they would understand if Shaggy and Scooby didn't want to forgive them. After reading the letter, Shaggy and Scooby were moved to tears. Scooby asked what they should do, and Shaggy replied that they should "let bygones be bygones". Suge agreed, and they all decided to move on from their past mistakes.
" So what did you guys do?" She asked
" We were at a school for girls " Shaggy says
" You're kidding " Sugie says
In Shaggy's room a chest was seen the chest of demons
the next day
Waking up at 3 pm, Scrappy was confused and called out to his uncle Scooby. Shaggy called out to him again and Scrappy replied with "Tadada Puppy Power!" He then ran into Sugie and greeted her with a "Hi Sugie". Sugie asked if he was finally awake and Scrappy replied with a "Yep". He then asked what was going on and the gang told him that they were sorry. Scrappy questioned if they were planning a prank on them and Scooby replied with a "Yes". Sugie then suggested that Shaggy and Scooby should get some milk. Scrappy then asked if they wanted to play a game, but before they could answer, there was a knock on the door. Shaggy exclaimed "Zoinks!" and Fred asked if it was him. Shaggy and Scooby then replied in union with a "Freddie!".
"Hey guys," Fred said as he came in. Shaggy asked again, "What are you guys doing here?" Daphne replied, "We have to talk." Velma added, "We saw you guys return." Fred then said, "Listen, Shag. I'm going to be a mystery writer in two weeks." Shaggy was shocked, "No way!" He then added, "Like Fred, we solved a mystery without you guys." Velma asked in surprise, "Really?" Daphne then proposed, "Should we reunite?" The gang paused for a moment, while Scrappy was hiding. He then asked himself, "I wonder when Sugie is coming?" Suddenly, he heard a TV and thought, "Wait a minute, is she?" Velma then said, "Meanwhile, we promise we'll stop our habits." Shaggy then declared, "Okay gang, I guess it's time for a reunion." With that, Shaggy and Scooby came inside with the gang. Sugie greeted them, "Hi bro, Fred, Daphne, Velma!" She added, "Long time no see."
Later,Velma apologized for the jokes, but when Scrappy asked why the gang left him and Shaggy behind for Fred and Daphne, she said they were too good for her. Shaggy accepted the explanation and then suggested they go investigate a moat monster haunting a nearby tower. Everyone agreed and Daphne wished them luck as they left. After their adventure, Shaggy said it was like the good old times and Fred asked if they wanted to go to the malt shop. Scooby was excited and said yes.
Suddenly a crystal ball was glowing as Daphne looks at it and lets out a small smile as she picks up " Hey Vincent " Daphne says as Fred and Velma was confused.
