Trude lives with a big, furry, super-strong creature. It doesn't know where it came from, nor how to behave in human society. Trude decides to show it her world to try and teach it - but as she teaches it, the creature's questioning of Trude's rules also opens her own worldview. A series of animated slice-of-life vignettes by Studio Soi (which also created the Gruffalo animated films), Trudes Tier originally broadcast as part of the German childrens' TV show Die Sendung mit der Maus.
