The small rocks are easy enough to smash. Same with the small branches.
The bigger smooth looking boulders that seem to pop up outta nowhere on your feild, are easy to break once your hammer's equiped with a yellow wonderful. but thats not what im having a problem with...

Its the Large rough looking boulders...and the tree stumps that also seem to pop up outta nowhere on the feild. No matter which wonderful (or sets of wonderfuls) i equip to my hammer,i cannot smash the large rough looking boulders. Same problem with the axe. no matter which wonderfuls (or sets of wonderfuls) i equi[ to my axe, i cannot chop the tree stumps.

Can anyone help? thanx
