Why did the bat go to the Halloween party?

Because he heard it was a real scream

Why did the black cat join a trick-or-treat group?

Because it wanted to purr-fect its costume and get some paws-itive candy

Why did the mummy refuse to go to the Halloween party?

He was all wrapped up in his work.

Why did the skeleton refuse to go trick-or-treating?

Because he had no body to go with!
