Bonus peg-board pictures

While playing Diamond Dash game in my iPad, I suddenly find the frame of the peg-board twinkles with stars. In a few seconds, rays of lights fly towards a few squares and when the latter are clicked by the mouse, a simple picture will appear.It may be a “heart”, a “key”, a "star", a “house” or something else.

So far, I have collected eleven of these pictures. Can you recognize what they are?
