I'm glad he worked it out!
My big girl "Sir kawaii" has always been a durpy eater and will try to eat the mouse from whatever spot she caught it in. Because she's so big now she just eats half of them sideways. Sometimes it will take her a half hour to eat because she has to bend it in half, but her stubborn butt takes it down. I remember the first time she decided to eat a mouse backwards when she was very young I was told to take it from her, some people might but I wouldn't suggest it.
If your snake has taken more than an hour to eat and doesn't have 1/4th of the mouse or rat down, and you feel the need to help, I then would contemplate how much is in its mouth and neck so far and how you would logistically remove it without scaring the snake. If your snake has previous anxiety and or aggression issues do not put your hand in there.
