Too Lazy to Aim is an achievement in Run 3.
The Skier's jumps cover the distance between the rings of crumbling tiles very precisely. With the Skier, just jump from ring to ring, avoiding the regular tiles, until you complete the achievement.
The Lizard also works well here too, due to its excellent maneuverability.
With the Runner, you have to use her long jumps and change gravity to get on the Crumbling tiles.
