Starbucks Japan vocabulary Q

What is the proper Japanese word for one of the green "Splash sticks" as their called in the US?

I have asked a few JP coworkers, and they all just say ささして or スティク while doing hand gestures.

I`d rather learn the proper word though, instead of gesturing like a moron.

curious.
I have never heard "splash sticks" and I thought it's "muddler".

I think their only called Splash Sticks because the clog the hole in the lid of your cup so there is no splashing when you walk with your cup, Vs a muddler which is used to mix (stirrer) a drink.

Oh, sorry. Of course, it's "splash sticks".

I just want to say...
maybe many Japanese don't know its name is "supurasshu sutikku" and they call it "madoraa", I think?
スティク they said, you said the word when you asked them?

Anyway, also I want to know that Japanese name.

I believe they are simply referred to as "muddler" (madoraa) or "Siren muddler" because of the logo :)
