Nickelodeon will be hooking iPhone and iTouch owners up this year, as it launches some applications. SpongeBob SquarePants Atlantis Treasures, a THQ game, came out this past week. A Dora the Explorer app, planned for a March release, will challenge gamers to match, count, and spell their way to the high scores. SpongeBob’s Wacky Walk and Shockwave’s Daily Jigsaws-To-Go will hit the system in April, and SpongeBob Diner Dash in July. Good stuff!
