Grumpy old farmer Jakob Krämer brings his listless blue macaw to new vet Kajo, grumbling its' not like doc Hansen, and is told to work out what changed in the physically healthy bird's life recently, so he blames indignant Martin Kalkbrenner, as he recently started feeding his bio-seed. While he's in the shop, the cage with the bird gets stolen. Liam joins the animal friends search all around Waldau, which finally retrieves it t he home of Marko's depressed mother, whom the knave hoped to cheer up, and the bird got over its stress there, inspiring the noisy real reason for its depression.
