In order for your starfish to get onto the glass, you have to have the foreground lights all the way black. If you are unable to do this, try turning up the background lights then finish turning down the foreground lights.

At this point, turn on wireframe mode and wait until the starfish "jumps" on the glass. Once it does this, you can adjust the lights to however you want. The starfish will only go back to the bottom if the foreground lights are turned down all the way.
