Bill Board

"Hey now! If you're thinking about just rolling that ball away, you'd better listen to old Bill Board here."

- Bill Board

Bill Board is a character in Super Mario Galaxy, one of four sentient Boards in the game. Of these four boards, he is the one to appear most often, constantly reminding or teaching Mario how to control the Star Ball whenever it is used in a section.

Bill Board makes his first appearance at the very start of Rolling Green Galaxy, situated right next to the Star Ball. Whether or not Mario views him before getting on the ball, he takes the time to give Mario (as well as the player) a tutorial on controlling the ball. This includes how to keep the ball stationary, how to turn, and how to jump while on the ball, often asking the player to try this out before moving on. After this, he allows Mario to either move on or speak to him again for a refresher.

Bill Board returns for the final section of Melty Molten Galaxy, which is also centered on navigating atop the Star Ball. He appears to recognize Mario, though insists on cautioning him for this section.

Bill Board reappears at the start of Rolling Gizmo Galaxy. This time, Mario is not required to initiate a discussion with him. Once again, he seems to remember their previous encounters, simply informing him the entire level revolves around the Star Ball and that it may be used to clear away any enemies or obstacles in his path.

For the Grand Finale Galaxy, Bill Board makes a reappearance halfway through, this time without providing any actual information. He simply compliments his surroundings, implying he is not fully satisfying with being a board.

Bill Board is the only one of the four sentient boards to make an appearance in Super Mario Galaxy 2, appearing at the start of Rolling Masterpiece Galaxy with virtually the same purpose. This time, he tells Mario to get onto the ball before he is actually able to do so, also referring to it as his starting position.
