Boards (Super Mario Galaxy)

Gil Board, Bill Board, Phil Board, and Jill Board 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.

Gil Board
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
Bill Board is the second board encountered. He teaches Mario how to play the Star Roll 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 wasn't a sign.

Phil Board
Phil Board is the third board encountered. He teaches Mario how to move when he is in a Bubble. He appears in the Bubble Breeze Galaxy and Bubble Blast Galaxy.

Jill Board
Jill Board is the fourth and final board to be encountered. She reminds Mario how to control his Boo Mario form. Her only appearances are in Boo's Boneyard Galaxy and Ghostly Galaxy, where she only speaks to Mario when he is in Boo form. There is said to be more than one Jill Board so that Boos can see what's happening around the galaxy.
