Captain Shy Guy
From the Super Mario Wiki
Captain Shy Guy is apparently responsible for the Lucky Space in Bowser's Warped Orbit. When the player lands on it, he makes use of the landing pad nearby and asks the player to hop in to his spacecraft.
They then reach what is known as Shy Guy's Orbital Buffet, which has a few Blue Spaces topped with three coins and a Candy between each one. This "Lucky Space area" does not lead to a free star, but getting to pick up three free pieces of candy. The Candy always turns out to be either Bullet Candy and Bowser Candy (three free pieces of Bullet Candy and Bowser Candy). When the player reaches the end, Captain Shy Guy returns the player to the Lucky Space to finish their turn.
Captain Shy Guy appears to be of some sort of alien Shy Guy species, as multiple aliens who look just like him dance around Shy Guy's Orbital Buffet.
