Second time we see the Green Ranger actually sit inside the Dragonzord instead of controlling it with his dagger. First time was in The Green Candle part 2.
1st time we see Billy wearing a sleeveless shirt and showing his muscles.
This episode originally aired the day after Jason David Frank got married to his first wife.
When zordon tells Tommy that he needs to conserve his energy of his powers he usually says to the rangers "may the power protect you " to them but it is Tommy that says it before he say "it's morphin time "
