Bubble popper Achievement
Pop 1000 bubbles
All bubbles in the game count towards this achievement, including the ones that contain vegetables, TNT, and pigs. This will most likely need a bit of grinding. The best level to complete this on is Level 1-26. There are 9 bubbles to pop and they can all be destroyed with a single, well-placed shot. See the video below for the technique.
