The Mystery Tunnel was a giant tunnel located at Chip 'n Dale's MiniGolf in Chip 'n Dale's Acorn Acres where Toons simply walked back to Chip 'n Dale's MiniGolf upon entering. Before the release of Bossbot Headquarters, the Mystery Tunnel was temporarily replaced with Bossbot Headquarters' dark ominous tunnel that led to "Barbecue Headquarters" as a prank during April Toons Week in 2015. Shortly after the release of Bossbot Headquarters, the Mystery Tunnel was ultimately replaced with its dark ominous tunnel.
During April Toons Week as of 2023, a new version of the Mystery Tunnel replaces the Cartoonival Grounds tunnel and teleports Toons to the interior of a randomized Toon Building.
