- "I'm here to teach you everything you want to know about pipes!"
- ― Piper, Pipe House, Mario & Luigi: Superstar Saga
Piper (also referred to Pipe Master) is a character in Mario & Luigi: Superstar Saga.
Piper is a pipe-inhabiting creature that resembles a Bullet Bill.
While the Beanbean Castle Town is peaceful, Mario and Luigi went into the Pipe House, they were about to go through the Red Pipe until Piper popped out looking pleased to see the Bros.. He asks them about what pipe do they want to ask about. When asking about Green Pipes, he explained to jump in one to another place to "elsewhere land". When asking about Yellow Pipes, it explained that they are travelled below the "seafloor and the surface or between above and belowground". If the Bros. allowed him to explain more about pipes, he greets them a goodbye. He told them to "study a little on their own".
