The Nintendo DS version of "Monsters Vs Aliens," based on the movie of the same name, offers younger players a series of adventure-themed levels featuring the movie's characters. One level features the movie's mad scientist character, Dr Cockroach, as host of a refraction-based puzzle that must be solved before the level can be passed. Solving the puzzle is deceptively simple, but requires careful placement of the mirrors given to you.

Skill level:


  1. 1

    Drag a mirror directly under the green circle closest to the switch.

  2. 2

    Place a mirror on the square to the left of the switch.

  3. 3

    Place the last mirror to the right of the green circle closest to the switch to complete the light's path over all the green circles.
