This is an extremely special Peach clinging to Mario 7 plush made by Commonwealth Toy and Novelty around 2010. Commonwealth never ended up releasing a line of Nintendo plushes but they did make prototypes of some designs. This is surfacing and being seen for the first time ever 13 years after it was made.
This Mario shares the same design as the lone Mario bean bag Commonwealth prototype which I have also listed. Please take a look at all photos to judge condition for yourself. Please message me if you want to bundle multiple listings into 1 at lower prices.
