Question about copyright laws

So recently I released an animation that sorta blew up (atleast by my standards) and attracted a lot of people to my tiny discord server. That’s besides the point. Anyways, as a joke we were talking about making DVDs with the animation on it, and only making like 10 of them and putting them on ebay for dirt cheap. Then people actually started saying they want them, and I thought it could be funny to try.

The issue, is that the animation is a fan animation of Weird Al’s “Albuquerque”, so we were thinking about issues regarding that. I’m definitely not educated on copyright laws, and I’m unsure about how we’d do it. Money is barely in the equation, if I have to give them out basically for free, I totally will. I just wanted to ask the experts here what the deal is with that.

Thank you!
