Tunnels

 is a new Expert Track in Bloons TD 5 iOS. The time for the towers to attack the bloons will be considerably short, as the bloons will go to the next path when they reach a tunnel.



Trivia

 * This track shares the aspects of Monkey Lane and Phase Portals:
 * The tunnels resemble Monkey Lane's tunnels.
 * When a bloon enters a tunnel, they "teleport" to another disconnected path, making it a harder version of Phase Portals.
