Straight from General Mills:
Thank you for contacting General Mills with your inquiry.
There are 6 different marbits in Shrek cereal and they represent the following: Shrek, Princess Fiona, Donkey, Gingerbread Man, Potion Bottle, and Puss ‘n Boots.
We hope you find this information helpful. Please let us know if we can help you again.

Apparently, it’s Puss in Boots and not Farquaad (from the previous post).
And I guess they are called “marbits” (?) and not marshmallows.
