The songs are as follows:

The title is "Song of Paradise Island". This song is the theme song of "Beautiful Trouble Again" in "Celebrity Detective". This song is more like whispering next to the ear: Hey, I found you, don't hide, you can't escape this Scarier than horror nursery rhymes, it has a completely different feeling.

The original song is "hide and seek". The original song is obviously playful and a little scary, but it turned out that "Celebrity Detective" talented people changed it into the version that everyone hears on the show now. It's probably a cover version with lyrics.

Excerpts from lyrics:

Ding dong, I have a secret that I will tell you quietly, welcoming you to the entrance to heaven. Ding dong, someone is ringing the doorbell, who is playing pranks as a game outside, listen, who is crying, look, who is whispering, there are a pair of eyes outside the window, they are watching you all the time.
