He-Man and the Masters of the Universe Season 2 Episode 36

He-Man meets a blind boy called Lous, whose friends consider him to be helpless just because he is blind. To give him a chance to prove himself, He-Man offers to take Lous on an adventure with himself and Ram Man, to the caves of the Singing Crystal. Lous accompanies them to the caves, but once inside, a flash of light blinds both He-Man and Ram Man. With all three of them blind, Lous uses his senses and bravery to lead them back to safety, across many dangerous obstacles.
