Happy Halloween indeed! I was very impressed by this animation. It's great to see a genuine crossover (mainly) between two properties. Did he not get candy because he wasn't wearing a costume? I mean, he had a mask on! I guess it still counts as going as himself.
Loved the "Salad Fingers" reference at 00:11. This was such a gorgeous looking cartoon. I feel sad I don't get trick or treaters anymore. The colors were wonderfully bright. This deserves to be watched on Halloween.
