The ghost introduces herself as Tippi. She takes Mikey to her world in the town of Fright Town, a place where monsters live. They run into Hannah and Tippi's witch teacher Hazel and she and Tippi want to show them that monsters are not all bad.

They meet the ruler of Fright Town the Grim Reaper as well as other monsters: Happi, Tippi's older sister, Dez, a zombie, Eva, a futakuchi-onna, Mr. Skully Funnybone the skeleton, Henry, a scarecrow with a pumpkin head, a fuzzy monster that works scaring kids named Peek-A-Boo, a vampire family of parents Count Vlad and Countess Ruby, and son Austin, and the :, , , and as well as their offsprings (the girls from ). Grim, Hazel and Happi are having another annual Halloween party, described by Tippi as the most "spooky phantom fest in the whole realm."

Antics include going into haunted houses, going to a scary carnival, teaching little vampires to fly, practicing spells, Bringing the dead back to life like Michael Jackson, and Mikey and Tippi crashing Grim and Hazel's party.

Later, Mikey and Tippi enter a dark house that belongs to the Boogeyman known as Martin, who scares and actually eats children. Martin reveals that he scares Jack every Halloween. After Jack tells Martin about Tippi's deception, he decides to put Jack and Tippi on a thriller ride to scare them. The ride frightens the two and they ran to the party. Martin discovers about Mikey's cousin and friends and plans to capture them.

Outside of the haunted museum, Holly, her friends, Johnny, Kat, Troy, and Dylan have waited for hours for Mikey to get Hannah out. The typical trick-or-treating time has passed, and Amy calls out Holly after the latter makes fun of her for believing in monsters the way Mikey does. Mikey and Hannah's mom tells Holly that she doesn't have to agree with her friends, but she shouldn’t stomp on their beliefs and Holly later apologizes to Amy that she has a right to believe what she wants and she respects that. As time went by, Holly, Carrie, Amy, Troy, Dylan, and Kat all become worried about Mikey's legends about monsters being true and that him and Hannah's lives are in danger. They demand to go in and get the two, but Johnny, out of nowhere, insists there's no monsters and tells them they all wait for Mikey and Hannah longer. However, Johnny's attitude quickly changes, and all four kids enter the house to look for the two.

Near the end of the adventure, Mikey tells the monsters about their adventure and about his obsession of monster hunting and fear of monsters which no one believes him. Amy's name rings a bell to Tippi, who scares Amy every other Friday; It is revealed that Mikey watches monster movies and it makes him spread rumors that monsters eat kids. Mikey, Tippi, Grim, Hazel, and their friends decide to play a prank on Johnny, Holly, Carrie, and Amy in response with Mikey's friends (who also met the monsters) pretending to be scared of them, which ends with Mikey pretending to scare away the monsters. It seem to work until Martin shows up and captures Hannah, Holly, her friends, and Johnny and Mikey's friends and locked up their souls. Which leads to Mikey and Tippi to confront Martin. Using the flashlight, a monster hunting phone, and the ooze TNT dynamite, Mikey creates a makeshift bomb, destroying Martin and releasing the souls of Mikey's friends.
