When Shrek married Fiona, the last thing he could imagine is that he could become the following king. However, when his father in law, king Harold, unexpectedly dies, that’s exactly what he became. If Shrek (with the valuable help of Donkey and Push in Boots) does not find a suitable king for the Kingdom of Duloc, the ogre will become king. Artie, Fiona’s cousin, an underachiever high school slacker, is the most promising candidate, but proves to be a real challenge for the three of them.
