Fullmetal Alchemist Brotherhood ED: Adventure Time remake

The first ending sequence of Fullmetal Alchemist Brotherhood remade with the world and characters of Adventure Time. A fan creation made with love, Movie Maker and suffering (in this order). See original: Song: Uso by SID I can’t find who animated the original sequence. Help? (EDIT: To be clear because I saw that some people in the comments were confused, I did animate this. It is entirely based on the first ending sequence of Fullmetal Alchemist Brotherhood and uses characters from Adventure Time. I did not make the song, it was made by SID.)
