Bug Stomper is an achievement which is earned for killing a total of 100 Grubs. Grubs are the small and harmless "critter" bugs that you can find on the ground. Simply walking over them will squash them for progress in this achievement.
- This achievement is pretty easy to get. Simply step on some grubs.
- Grubs follow you if you are close, making it even easier to find them and step on them.
