Donkey

"Donkey begged 'Shrek, what has come of you? My realm lies in ruin yet you do not rebuild it?'"
Donkey is the 4th being brought into existence. He was birthed when Shrek sculpted him out of his own astral fecal matter. Donkey is the observer of Midgard, and serves as Shrek's right hand man, and steed.
