Season 1 - Episode 10 Train and De-Train
A small boy runs across a field into a forest, snapping a stick of a tree as he goes. Stick in hand he pauses by a tree to catch his breath while looking around the forest. He hears a noise from the tree above which scares him and he runs off. He sees a squirrel in the tree and throws the stick at it and hides behind another tree. He makes his way up the tree trying to reach the squirrel he threw the stick at. As he gets close the animal falls stiffly from the tree. The squirrel lies dead on the forest floor.
