Robin Goodfellow's ice hockey requisites (5)

I believe the answer is:

pucks

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

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

'robin goodfellow's ice' is the wordplay.
'robin' becomes 'puck' (Shakespeare character Puck or Robin Goodfellow).
'goodfellow's ice' becomes 's' (I can't explain this - if you can you should give a lot more credence to this answer).
'puck'+'s'='PUCKS'

Can you help me to learn more?
