At the end of the episode, you play as Batman escaping the Penguin's exploding airship. After the level is completed, the Batplane is shot out of the sky.
Episode 5 - The Joker is who shot Batman out of the sky. Batman must stop him in the final battle of the game.
Gameplay in Batman: The Animated Series is fairly simple. The A and B buttons are for Jump and Punch Respectively. Both Batman and Robin have access to a wall jump ability that is extremely helpful when trying to reach higher ledges. Both characters also have access to Batarangs which must be found in levels. These are toggled on and off with the Select button. Batman has the ability to use a grapple hook, while Robin can hang from ceilings. Batman can be hit seven times before losing a life, while Robin can only be hit five times.
