- “See my Minimizer here? Guess what it does! It shrinks you all down to size!”
- —Bowser, Mario Party DS
The Minimizer is a magical staff that Bowser uses in Mario Party DS. In the beginning of the game's Story Mode, Bowser shows Mario and the crew the Minimizer and shrinks them while stealing Mario's Sky Crystal. After Bowser's Pinball Machine is cleared in Story Mode, Donkey Kong and Diddy Kong arrive at Bowser's Castle for dinner. Donkey Kong breaks the Minimizer, reverting the shrunken characters to their normal sizes. Bowser then fights Mario and the crew without his Minimizer.
