S1E65 The Heart of a Giant

Adam, Man-At-Arms, and Orko venture into the forest in search of Salkweed for Man-At-Arms' experiments. Suddenly, a storm hits, and Orko finds himself lost and face-to-face with a giant. Overcome by fear, he faints, but when he regains consciousness, he discovers the giant has brought him back to his friends, along with a stash of Salkweed! Just as they begin to question the giant, he departs. Soon after, both Orko and the giant are captured by the proprietor of a traveling Freak Show, who profits from displaying strange beings. As He-Man races to save them, the giant devises a clever escape plan, revealing his surprising intelligence and kind nature despite his imposing size.
