This episode conjures up internet cats like you've never seen them before, a jazz ensemble made entirely of bird puppets, a Peckham auntie who reclaims the streets on horseback, and opera reimagined as a partially-nude fantasia. Plus: the menstrual underworld awaits in an animated music video for Swedish punk ShitKid.

This episode features painterly animation and the first dance filmed in Antarctica. Social media gives an animator the blues, bodies collide in new configurations in an elegant movement piece, and there's a vivid reflection of a fractured mind. Plus: cut-out animation of a gender-neutral plant.
