Name of "Intro Music" in Hotel Man's "Do not be Scared" ?

Could anyone tell me the name of one song…?

Gaki no Tsukai - Hotel Man Batsu
Part 2 - if you have the video split in two parts, it’s at 02:04:23.

This is during the "Do not be Scared" annual series. It is one of the traps knows as "Intro Music" just before the ending. It starts when the tram enters the room, where the offering is being held… Can anyone tell me the name of it, please?

Does anyone know the name of the intro song that plays in the first Gorenjai game ?
I am not sure for this name…
