Nintendo on Tuesday unveiled two special editions of its DS handheld gaming unit in an effort to to keep up fans' enthusiasm for the device heading into the holidays. One version will be colored gold and come with the epic adventure game "The Legend of Zelda: Phantom Hourglass" while a metallic pink model will come with puppy training title "Nintendogs," Nintendo said.

The new bundles will go on sale in the United States on November 23, the "Black Friday".

Nintendo DS is available in black, pink and a crimson-black combination colors. With its touch screen and mix of advanced and easy-to-learn games, the DS has been a cash cow for Nintendo, selling 4.5 million units in the United States so far this year at about $130 each.

A DS and one game normally costs about $160, but Nintendo said it will let retailers set their own prices for the new bundles or offer them with more accessories.
