Police are issuing a special warning for children going trick or treating tomorrow night.
They have created a YouTube video for kids with guidelines on how to keep safe on the spookiest night of the year.
The star of the video - Brooke - helps to share the messages police want to get across.
"If people have signs saying 'no trick or treaters', it's nice to leave them alone. They probably wouldn't have yummy lollies anyway."

Brooke's other hot tips include taking a parent out trick or treating, and not going inside any houses.
