Your last name is Castanon? I never knew that! Anyway, I had no idea what that creature truly was. I'm just going to say his true form was the squirrel. I mean, I'm reminded of Squirrel Girl being the most unbeatable superhero ever. Yeah, look that up!
That is a good lesson to teach kids. You would get their candy either way! Just do it the courteous way. Wait for them to give it to you. The animation was amazing too.
