Yam Yam is playing on a pile of rocks and accidentally causes them to roll down a slope, blocking the entrance to a cave, which happens to be a bear's home. The bear returns home but can't get to his food, which is in the cave. Just then Gully walks by with a jar of honey, and the bear follows the scent of the honey. Gully arrives at the farm and puts down the jar of honey whilst she goes to get some eggs. The bear picks up the unguarded honey and walks off with it. Gully enlists the help of Pi to solve the mystery of the missing honey and they follow clues which lead them to the bear cave, where they find the bear with the jar of honey. Gully finds out that the bear can't get into his home and Ruddle and Yam Yam help to unblock the cave entrance. The bear gives them some fruit to say thanks.
