Ok, still underground, but close to the surface once more. Laser eyes won't light em' up, but the M.O.A.B. (Modern Ordinary Air Blimp, not Mother Of All Bloons) has bright headlights that will cause it to show itself. Oh, and also don't worry about losing turrets, cuz they're stored in a special inventory where u can get them back, but it costs 50 bloon bucks to open it each level. Heh heh! Oh, 1 more thing! Monkey Glue, spikes, and wrongly timed pineapples will just burn your budget up.
