Halloween "tricks"

[Biggles001]

Does anyone have any fun/innocent "tricks" they can share just in case my DD is met with any "trick" requesters?
(No eggs or flour throwing please, and yes, she will only be knocking at houses that are decorated!)

Putting her mask on and making scary noises.

My parents decided to say "trick" once, to a couple of children who turned up. The children were dumbstruck! My dad then said "you should try to make an effort to scare me, put your masks on!"
