Boing Sound?

[Ceomandala]

I'm on SE just in my house ans twice I hear this "boing sound" like a spring or something? Anybody else experience this?

If you have an oviraptor it could be the egg gather sound it makes.

I just heard it too. I have no idea what it is. I opened my fridge and heard it.
