It’s an Oompa Loompa whistle. It’s the only way you can get their attention.
Which Willy Wonka? The 1970’s GOOD one?
Regardless, I believe it was a special Oompa Loompa whistle; Similar to a dog whistle.
I know that he uses a piccilo to open doors, which is really badass
@aanuszekl: Perhaps the only time that the words “piccilo” and “badass” will be coupled together in a sentence :-)
@bear I think you may be right.
I want a Wonka whistle!! Although I fear who might show up when I blow it! ;)
