Purple Box Surprise

This mission model has something hidden in a purple box at the top of the model. To reveal the hidden object, the robot must press down a red trigger at the front of the box. When it does so, the hidden object, a star, pops up. The thing that's nice about this mission model is its bistable nature. The mission is either solved, or not solved. There is no in-between. Plus, the model is very sturdy. And, it's pretty small, so it wouldn't take up much room on the field.
