The kids and Violet chased after Mike, and when Mike got to the door, he opened it and saw the sludge monster behind it. Then the beast shape-shifted into a bat and scared Mike. Mike fell to the floor while the monster flew above his head and watched him scream. Then Emma used a net from the closet to catch it. Once he got caught, the beast shape-shifted into a tall tree and tore the net. Then it shape-shifted back into itself and saw Sam holding the spell book. The monster got mad when he saw Sam with that book, so it shape-shifted into her mother and walked up to her. Sam screamed because she was afraid of her mom.
Then, the monster grabbed Sarah's spell book from Sam and pushed her down. The beast said, "Daughter, you may have the book back when you learn to be more intelligent." Emma said, "You're not my mother." Emma jumped and grabbed the book. Emma skimmed the book and tried to see if there was a spell to stop the monster. The monster ran to Emma disguised as Sam's mother and took the book from her. Then Alex took the text from the beast. Alex said, "Mine." Alex ran away, but the monster ran up and swiped the book from him. The beast said, "I don't think so." Mike said, "I do." Mike jumped, kicked the monster, and took the book. Once they had the book, they all ran out of their room and hid in another room.
Once they got there, they saw a wall dripping blood. When the kids and Violet saw the blood on the wall, they opened the door and saw the sludge monster. Once they did, they all screamed in terror. Then they all hid except for Helga. When the beast realized what Helga was afraid of, it shape-shifted into a clone of herself. Then the monster took off its head and held it underneath its arm. The monster's head said, "Hello, Helga." while its body waved hello to Helga. Then the beast held its head up to Helga, and Helga screamed and ran for her life. After getting scared, Helga ran into the dining room and hid underneath the table covered with a sheet.
The others split up and tried to find Helga. When Bobby got into the kitchen, he looked in the kitchen for her. Then he heard someone open the door, and Bobby looked behind him. When he saw who it was, he saw it was the sludge monster. Bobby started to get worried, and the sludge monster hissed at him. Then it melted and shape-shifted into water. Then the whole kitchen started to fill up with water, and Bobby got worried he would drown in it. Bobby ran for the door, tripping and falling deep into the water. Bobby swam back up to the surface and started to panic. He jumped on top of the stove, but the water kept rising. Then he jumped on top of the refrigerator, but he saw the water level just kept growing. Then Sam heard Bobby scream, so she ran to save him. Sam put her ear on the kitchen door to listen in on what was happening. Sam said, "Helga?" Bobby yelled, "Sam!" Sam yelled, "Bobby!" The water level reached the top, and Bobby started to sink to the bottom. Sam pulled on the door and tried to get in to save Sam, but the door got stuck due to the water level inside. Sam yelled, "Bobby!" When the monster heard Sam, it escaped through the air vent while Sam opened the door. Bobby hit the floor, and Sam helped him up while he coughed. Sam said, "Are you ok?" Bobby said, "Fine." Sam said, "Come on, let's get out of here before that monster returns."
Sam and Bobby tried to leave the kitchen, but the door locked itself when Sam shut it so that they couldn't get out. Sam said, "We're trapped." Once Helga and Mike saw the sludge monster, she took a toy ax she found and threw it at the beast. When it got hit, it growled at Helga and Mike. Then it shape-shifted back into Headless Helga, but Helga ran up to her and grabbed her. The monster hopped on one foot backward and crashed into the TV. While Helga was holding onto the beast, Mike grabbed Helga and told her to let go of the monster while the monster tried to shake her off. Mike said, "Helga, stop." Then Violet came out and tied Headless Helga's legs to a rope. Then they all fell to the floor, but the monster turned back into a sludge monster and slithered out of the strings. Then it slithered out the door. Helga said, "It's getting away." Violet attacked Helga because she wanted to go after the monster. Then Helga threw Violet off of her and asked her why she did that. Violet said, "Are you crazy? That thing knows what you fear. It's best to leave it alone. Plus, why does it shape-shift into a headless you around you? Are you scared of yourself?" Helga said, "No. I'm scared of dying. So that thing turns into me already dead." Violet said, "Well, if that thing finds you, you'll die."
Once Bobby and Sam had opened the kitchen door, they started to look for the others. Meanwhile, Alex and Lou were also looking for the others. Alex and Lou opened a door and found a room with a pool. Once they let go of the door, it slowly started to close. Once it slammed shut, the noise was so loud that Alex and Lou screamed and hugged each other. Then they began to get a little scared, but Lou started to calm down when she sang a song her mother always sang to her whenever she was afraid. While Lou was singing, two giant arms came up from behind Lou, and Alex started to get scared. Once he saw the massive arms, Alex pointed at them and tried to warn Lou while she was singing. Lou was wondering what Alex was referring to and looked behind her. Once she did, she saw a giant clown come out from behind a pillar, and she screamed. Then Alex jumped in fear and landed in the pool. Lou yelled, "Alex!" Alex started to drown while the monster disguised as a clown came at Lou.
Lou climbed up a pillar when the giant clown had her corned, and then it tried to grab her. When Lou got to the top, she saw the diving board of the pool and the big clown coming at her. Then Lou jumped, and the giant clown destroyed the pillar she was standing on. Then Lou jumped off the pool's diving board and up to the side of the wall. Once she got up there, she held on for as long as possible. Mike yelled, "Alex! Lou!" Susan cried, "Where are you?" Once the monster heard them calling, it shape-shifted back into itself and went to find Mike and Susan.
