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 and Nat to get Hannah out. The typical trick-or-treating time has passed, and Amy angrily 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 Nat's legends about monsters being true and that him, Mikey and Dani's lives are in danger.

It seem to work until Martin shows up and captures Nat, Dani, 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.
