The Achievement is located in the third chapter called "Berry mire"
The first Mosquitoes are after the second collectibles and there will start the achievement. The key to success is control the Mosquitoes. You can go back and forward to bring the Mosquitoes where you want. The most important part is, if you are surrounded by Mosquitoes DONT USE RT
or the achievement is gone.
Try to use many as possible
. At some points there is no other option, you have to use
, make sure you are not surrounded! If you are surrounded, go back and try again. Of course speed is useful but control your situation is for me the key to success.
