The Bloonchipper's Bloonprints are found inside a cave. It's a special mission and this means it's extra difficult. You are going to need at least 1900 starting cash and 85 health. The track starts from 1 entrance and splits into 2 tracks. The left track takes 2 right turns which makes a 180 degree turn. The right track splits into 2 left turns. Both tracks take a 90 degree turn towards the Bloonprint and are parallel. At the other end, the left track does a 90 degree turn and then takes 2 right turns back to the Bloonprint. On the right side, the opposite happens.
When you start the game, put 2 Dartling Guns and aim them at the entrance. Place these after the second 90 degree turn and before the next turn. One should be on each side. You can get a supply crate if you don't have enough cash. Upgrade them to Powerful Darts as soon as possible. DO NOT UPGRADE ACCURACY! The spread of the guns help destroy more Bloons. This should be done by round 3.
After the Dartlings are finished with, place 3 Glue Gunners and upgrade them to 2/1 (Corrosive Glue/Stickier Glue). Set them to Strong targeting so that they can hit the Ceramic and Rainbow Bloons that are going to come. These must be placed right at the entrance. This should be done by Round 6.
Next, place the good old Dart monkeys. Upgrade him to 2/3 (Enhanced Eyesight/Triple Dart). The Triple Dart is crucial here. They must be placed right behind the Glue Gunners and next to the third set of 90 degree turns. This should be done by Round 10.
Now you would be encountering tougher Bloons like Ceramics and Rainbows. Now, you can put 1 Dartling Gun in between the 2 others. This must be done by Round 14 - 15. Now beware, a MOAB comes in Round 15. It will come on the left track so move your finger to aim at the MOAB and its children. If all goes well, you should win with minimal loss of life. If you don't feel confident about your Dartling aiming powers, put down some Road Spikes, White Hot Spikes or just drop a Pineapple.
