S1, E11: Herbert the Shire horse thinks he has lost his strength. He goes to Wissper hoping she will bring it back. They travel to the river where Herbert has been trying to haul logs for the beavers. He can’t seem to shift them at all. It’s another job for Dan the panda who takes an unusual view of what’s going on. He and Wissper work out that Herbert has got his vine stuck in a tree. Free the vine and Herbert gets his “strength” back.
