This is how the post credits scene goes in Horrificator (CTaRAoMToLaCN).
[at night, Evil Ryan saw the Screamin' Banshee and Tow Horrificator]
Screamin' Banshee: [growls]
Tow Horrificator: [growls]
Evil Ryan: [gasps] You two better run. I heard there was a Banshee and a Tow Horrificator out there somewhere in Paris, but, I haven't seen them yet. Good luck. And good night.
[Evil Ryan sets off to Alya's house]
Screamin' Banshee: Huh?
Tow Horrificator: Did he just warn us about us?
