Mystery Marshmallow

Shrek Cereal is some good stuff! It’s a bit like a combination of Lucky Charms and Kix (kinda like Kix w/marshmallows). I just am a little confused by the shapes.

I think I’ve got them all down but one. 1.) Donkey 2.) Gingerbread Man 3.) Princess Fiona? 4.) Farquaad 5.) ???? 6.) Shrek

So what on earth is marshmallow #5? Maybe an onion? A blue throwing grenade? …no idea!
