Gray Rock

Gray Rocks are obstacles in " Mario & Luigi: Superstar Saga". They are found throughout the Beanbean Kingdom, serving as roadblocks for Mario and Luigi. They can be destroyed by Super Hammers and Ultra Hammer s (which are forged by the Hammerhead Bros. at their home in the Beanbean Castle outskirts), but not regular hammer s. A Gray Rock blocks the entrance to Teehee Valley, and must be destroyed to pass through.
