This activity allows the child to practice managing the pressure on the stylus, especially the weak and strong pressures present in writing.
During this activity, the child will have to use the stylus like an archaeologist's brush and scratch the ground to find hidden objects. If the child presses too hard, they will break the object, while if they do not press hard enough, they won't dig deep enough into the ground and therefore does not reach the object.
When the objects found are sufficiently "clean", they must confirm by pressing the button located at the top left of the screen.
