Johnny Test was horrified to find out that his sister, Mary Test, was running away to the Haunted House because he thought that Horace N Buggy yelled at her too much.
"Horace told us not to go there!" said Johnny. Horace did not listen.
"Johnny, no! It's too dangerous!" said Dukey, trying to keep Johnny from getting involved.
"Mary could not make it if she stays there. I'm bringing her back right now!" said Johnny.
"Go on, Johnny. I do not care what she thinks about us. Just bring her back!" Dukey agreed.
Dukey was on Johnny's side. "She can do it on his own. She's done it many times before." He said.
Dukey and Johnny set off for the Haunted House where Mary was hiding and entered. There, to their horror, they found Mary.
Dukey threw garlic at Mary's head.
Mary got hit by the garlic. "What just happened!?"
"Dad told us not to go to The Haunted House!" said Johnny sternly. "There are monsters like vampires, werewolves, bear beasts, mummies and dragons!"
"I told you not to come after me!" Mary scowled. "I had to run off because Daddy and Mommy yell at me all the time!"
Vampire Gumball noticed them. "Hey! A thirteen year old girl!"
"Let's get out of here!" cried Dukey. Johnny put Mary on his shoulder and began to run.
"After them!" yelled Vampire Gumball. Various monsters chased Dukey, Mary, and Johnny until they ran out of the house. They immediately ran home.
When Dukey, Mary, and Johnny made it back home, Johnny caught his breath and told his parents, Hugh Test and Lila Test, that he saved Mary for him. Hugh was grateful to tell Lila about it. "Johnny did it! He saved Mary!" He turned and scowled at Mary. "Mariella Samantha Elizabeth Test, what were you thinking? You could have been turned into a monster!"
Mary glared at him. "I do not care what you think of me, Daddy! I had to run off to the Haunted House because you yell at me all the time!"
"Mary, you have to learn to behave like Lumpy, Roo, and Susan do." said Hugh sternly. He turned to Johnny. "Johnny, thanks for saving Mary." "You are welcome, Dad." Johnny said.
Mary shrugged. "It was nothing, Daddy. I was supposed to go there."
"Good going, Johnny." said Dukey. They did the fist bump.
At 10:30 pm, Hugh and Lila were proud of Johnny for saving Mary from the Haunted House. For doing so, Johnny was rewarded. For his award, Johnny was given grilled cheese sandwiches and french fries. Johnny was happy. He hugged and kissed Hugh and Lila and told them, "You're the best parents, Dad and Mom."
