Hey guys, I need to identify the origin of laughing SFX from those videos:

Version 1:

https://youtu.be/X6bv85hoQBM at 0:16

https://youtu.be/V46KYxFav24 at 3:21

Version 2 (sounds like coming from the same person, but it's different)

https://youtu.be/X6bv85hoQBM at 9:22 and 3:24 (with reverb effect)

Maybe someone heard this in any game/film/cartoon/sound library/etc?
