How does Bruno plan to get into the camp unnoticed?

Bruno plans to get into the camp unnoticed by wearing the striped pajamas he sees the camp children wearing. He believes that if he looks like them, no one will question him or stop him. Additionally, he intends to sneak out of his house and approach the camp during the day when fewer people are around. His curiOSity about the camp and his desire to meet Shmuel motivate him to take this risk.
