These are my super effective non-traditional strategies for Tunnels.
Tunnel Destructor

This one is tunnel breaking!

Gates to Bloon Hades

Which do you think is worse; Azapop or the Monkey Devil?

Tunnel of Destruction

These strategies are like 2-edged swords, aren't they?

Doomed Tunnels

You think this is expensive, wait till you see how much it costs to summon Azapop!

Tunnels strategy

Not even the tunnels will save the bloons!
