After The Energy Plant

You are in control of Batman and Robin. Head towards the screen to reveal a lift. Get on it, then use detective mode to reveal a Robin chute. Use it, then crawl through the vent. Pull the lever, then return to the Batcomputer. Hop in the Batwing and fly up to the bomb, then grab onto it and place it on the slot. Repair it, then build the Batcomputer to start the next level.
