When critters have seriously perplexing questions, they ask Sirius.
What are some good Halloween costumes, Sirius?
Sirius, who should I go trick or treating with tonight?
A.) Your friends
and your mom
and dad.
Who should (unfortunately) not go outside today, Sirius?
and this guy. This guy should definitely stay home.
How should I decorate my pumpkin, Sirius?
