Unused Polly Shot
The JumpStart website circa 1996 included this shot of Polly in her father's secret chamber. The equivalent shot in the final game has Polly posed differently and an image on the monitor.

Incidentally, the back cover of JumpStart Summer Vacation Activity Book for 3rd Grade included an image of Polly that was clearly derived from this unused shot.

Ms. Winkle/TransQuizzer Prototype
One of the game's digital manual images depicts an early design for Ms. Winkle and the TransQuizzer.
