Shy Guy (Mario Party 4)
From the Super Mario Wiki
Shown in the game's credits, Shy Guy appeared as a normal member of his species until he, Toad, Goomba, Boo and Koopa Troopa discover a blank cube on top of a Warp Pipe. The four decorate the cube with drawings of themselves. A Lakitu shortly arrives, holding an envelope on his fishing rod. Shy Guy and the other hosts see that the envelope contains party invitations and they proceed to dress in costumes and hold a party for Mario and his friends. In the game's opening scene, Shy Guy and the other hosts appear before Mario to deliver the invitation for the party.
Like the other hosts in story mode, Shy Guy offers a present to the player when they complete his board. When the player beats his board, he challenges the player to a game of Archaeologuess before he gives the present. Upon defeat, he gives the player the promised present.
Shy Guy is portrayed as a meek and nervous character, similar to his species' namesake. He reveals a longing to go on real adventures, but admits he's not bold enough to do so, leading to the design for his personal board. He dresses in a brown fedora hat and brown explorer's jacket, making him heavily resemble Indiana Jones. He often speaks in a nervous manner, frequently uttering "Umm"s and "Uhh"s in his speech.
