Roll into the Cage
From the Super Mario Wiki
Roll into the Cage is the first mission of Tick Tock Clock in Super Mario 64. In Super Mario 64 DS, the mission was replaced with Luigi in the Cage. This mission can be done at any of the clock's speeds.
Mario has to climb up the clock until he reaches the spinning platforms past the first hand. Past the spinning platforms is a conveyor belt leading into a cage. The mission's Power Star is inside the cage in plain sight.
