Toy Idea: Princess In The Tower Game - Combination of computer game and toy prison

The 'Princess in the Tower' game is a form of electronic handheld game which is also a toy prison for an action figure.
In order to open the toy prison and release the princess action figure you have to win the digital computer game which would be a fantasy quest to save her from the tower.
The action figure is behind a transparent door on the machine and as soon as a player wins the game, the door would either pop up or perhaps slide open revealing  the action figure that a child could then take out and play with.
Variations on the game: The princess in the tower idea could work in other forms, for example, instead of a princess the machine could release a sacred artifact that the player is questing for or it could even be a sports game that releases a trophy.
