odd sound during bonus on Candy Crush Soda

I have heard a weird bong sound when I was watching a bonus video and during my candy crush soda game. I have no clue where it originated, just that it happened 3 times! Nothing on my Ipad was responsible for the sound.

Does anyone have any idea or has it happened to anyone else?

Idk I keep sounds offing my game because they distract me
