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, the object breaks and they lose points, but if they don't press hard enough, they don't dig deep enough into the ground and therefore don't reach the object.
When the objects found are sufficiently "clean", they must confirm this by pressing the button located at the top left of the screen. The more accurate the excavation, the higher the score.
