I noticed 3 times - & All by Women! 

First Chef hit his hand to stop him when he was reaching for the Trolls she brought when she came back into the castle.

2nd time his hand got hit by Bridget in the 'Pizza Scene' ( but he found her 'Fantastic' anyway!  ^_~ ).

And 3rd time - Chef again! ... - She hit his head with a spoon at the end of the movie to make him open his mouth when she was trying to force him to eat a Troll.

Poor guy!  ^_~  - I think a King shouldn't be treated like that! 👑

( & I was sorry for him at those moments!  ^_~ )
