Conor gets carried away during a game of dress up at the school and his pirate voice is too loud. When the game turns into a treasure hunt to the Pirate Cave Conor’s shouting causes even more trouble – it echoes off the cave walls and wakes up baby bat Eduardo. The children have to help the bat family sing a quiet lullaby to get Eduardo back to sleep. Conor learns that you should always use your inside voice when you’re inside.
