RABBIT AVENGER Trophy
Kill more than 100 enemies during your journey. It's absolute slaughter.
This trophy should naturally come over normal gameplay during the 140 levels you must complete to acquire the other trophies. If by some chance you don't have this one by the time you acquire all the others, then you will need to load into additional levels and kill all the enemies present in each level.
There are three types of enemies you can kill: Those that walk, those that fly and those that climb the walls.
