Boards (Super Mario Galaxy)
From the Super Mario Wiki
“Your world is so cool! If only I weren't..a sign.”
The Boards in the Super Mario Galaxy games are four sentient signposts capable of speech. In Super Mario Galaxy, they tell Mario how to perform a particular move each time he meets them. Some boards appear in multiple locations, but their ability to transport themselves is not explored. The names of all four are puns on "billboard". The boards also appear in Super Mario Galaxy 2 with the same role as in the first game. In the Supermassive Galaxy, rather large boards appear on the first planet.
Gil Board is the first of the boards to be encountered. He is a signpost that tells Mario how to Wall Jump. He claims to be the "Famous Gil Board" and claims Mario knows him, although Super Mario Galaxy is the first appearance in which he has been specifically named. He appears in Honeyhive Galaxy.
Bill Board is the second board encountered, and the Board with the most appearances. He teaches Mario how to roll the Star Ball in the Rolling Green Galaxy, Melty Molten Galaxy and Rolling Gizmo Galaxy. He also makes an appearance at the celebration in the Grand Finale Galaxy. Here, he tells Mario that he lives in a nice world, and that he would be able to enjoy it more if he was not a sign.
In Super Mario Galaxy 2, he appears in the Rolling Masterpiece Galaxy, once again teaching Mario how to roll on the Star Ball.
