JumpStart Adventures 3rd Grade: Mystery Mountain/Pre-release and Unused Content

This is a list of pre-release and unused content from JumpStart Adventures 3rd Grade: Mystery Mountain.

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.

Basement Landing Graphic
A simple graphic saying "Basement Landing" appears in one of the resource files. It is presumably a placeholder graphic, but its purpose is unclear.

Time Machine Prototype
The JumpStart website circa 1996 included this image of Mort as one of the Missing Robots. In the final game, Cosmo-Bot is the robot retrieved from Poland, 1531.
