This is usually a sign of improperly digested meals, which result in diarrhea.
Ive had snakes do it 2-3 times in a row then went back to normal solids. Just ispect it each time if it continues for any worms. If its a non stop thing then may need a deworming just to be safe.
5 Jumbo's?! That is a little much, could be why it's not digesting properly. Switch to bigger pray if you can, rats would be good at this point.
This is why I never feed mice at all.
