Hi everyone,
This achievement has a pretty high ratio considering it is very easy to obtain. Just a teensy bit grindy.
First of all play chapter 1 for a bit. You have to reach the first 'boss level' (Wall of pigs). This will be after you have completed level 11. In this boss level you get 6 Stella birds. Just shoot them and make sure you use her special ability. To do so tap the screen on a block of ice or wood to make her change direction. She will speed off into that direction and bounce off the block you just tapped.
Now for the grindy bit

. You have to do this 200 times. When using all 6 Stella birds on this level, you will have to play this particular level 34 times.
Take note: there's also an achievement for doing 1,000 bounces with the Stella bird. This one is also best done on the first boss level (at least if you want to grind it).
Cheers,
Eddie
