Okay, I've got one.
In Australia, we call them hundreds and thousands.
In US, I believe you call them sprinkles.
What do they call them in the UK?
Edited cause I pressed enter too early.
In the UK, hundreds and thousands.
A word on napkins: in the UK, there's a well-known class division between napkins and serviettes. Both mean the squares of fabric or paper that you use to wipe your hands and lips on at the dinner table, but 'napkin' is posh and 'serviette' is lower class. A lot of people are quite surprised, as 'serviette' sounds more fancy—but that is actually the reason!
(I have a personal belief that a napkin is a classy thing, either made of actual cloth, ideally damask, or of nice, thick, soft and absorbent material if it is a 'paper napkin'. In my personal dictionary, therefore, there is no such thing as a serviette that is not made of paper, and to me, a serviette is one of those shiny, completely non-absorbent squares of white paper you get given with fast food and at motorway service stations. Sadly, these definitions are not shared with the rest of the world.)
