From Cartoon Brew:

Axolodyssey is a hand-drawn animated short from Studio Fresco Animation, an independent collective of artists working across studios and countries. Animated entirely in TVPaint, the film brings together contributors with backgrounds ranging from major U.S. studios to smaller outfits in Europe and Asia, all collaborating on a project that began as a personal idea during the pandemic and gradually expanded into a full production.

Directed by Jon Densk, the film follows Jojo, a young axolotl left alone in a fantasy-inspired version of Mexico’s lakeside ecosystems. As he sets out to find his lost family, the story unfolds as a journey through unfamiliar environments populated by strange creatures, fleeting companions, and looming threats. Alongside its adventure framework, the film draws on real-world inspiration from the endangered status of axolotls and their native habitat, grounding its fantasy in an ecological context.
