The Stone Prison
From the Super Mario Wiki
In this mission, Paper Toads are trapped in crystals atop elaborate stone structures, and Mario and co. must hammer the stones on the ground in a specific way so that the Paper Toads are lowered to the ground, but at the same time not crushed by a falling stone. Should a stone fall onto a Paper Toad, Mario and co. are given two more tries on the mission, and failure on the third try results in a "Too Bad!"
In the Hard Mode variant, more complex stone structures are encountered.
