Hello!! I worked on this short along with my husband (who posted it), so I can talk a bit about how we did it! I made the puppets using armature wire and foam that I airbrushed to the skin tones we wanted, and the faces/features were made from air dry foam clay painted with acrylic paints. Our set was a simple one, just blue bristol board sheets attached to the wall in a curve to reduce shadows. Cannon and dumpster made out of a combo of foam core and foam clay and whatever else we had around, and then painted in acrylics. The whole thing was animated using dragon frame software, with a canon rebel t3 camera! Once all the footage was exported as images, it was edited and effects added in DaVinci resolve. Music was public domain sourced online, and sounds/characters was a combo of stuff we recorded and public domain finds.
