Blue's Treasure Hunt was a game on the PC for Windows 95 and Macintosh first released on September 28, 1999, based on the Blue's Clues Season 3 episode "Blue's Big Treasure Hunt".
Although the game's premise was fairly similar to the episode, in which Steve and Blue receive a mysterious letter from a unknown person that leads them to find and follow clues that lead them to the Land of Great Discovery, the narrative of the episode was slightly altered to fit the needs of the gameplay.
Around the years of 2002-2004, an online version of the game was located on the gaming section of the Nick Jr. website. The mechanics of the online version were very similar to the CD version, such as both being point-and-click adventure games, although the online version had much shorter gameplay time. No screenshots are known to exist of the online version.
