Hi Speedrunners! I created an account here to ask my question : )

I came across this video here at timestamp 6:45:20 he uses the music box for fun in world 8 and then gets No Hands.

Makes sense that it would put them to sleep, no?

is that just an accident, or a well known technique (I tried googling but found nothing) or is it something that could work and be useful?

Greetings, TestPractice
