I'm a little stuck... Click here to teach me more about this clue!

'biscuits' is the definition.
Although both the answer and definition are plural nouns, I can't see how one could define the other.

I cannot understand how the remainder of the clue works.

Can you help me to learn more?

(Other definitions for yo-yos that I've seen before include "Toys with spool and reel" , "Playthings with spool and reel" , "Children's toys" , "Toys with pair of joined discs and string" , "1930s spinning toys" .)

I've seen this clue in the Sydney Morning Herald.
