Ice cream all the players must provide nearly half of? (5-6)
I believe the answer is:
tutti-frutti
'ice cream' is the definition.
(I know that tutti-frutti is a type of ice cream)
'all the players must provide nearly half of?' is the wordplay.
I cannot really see how this works, but
'all' could be 'tutti' (I've seen this before) and 'tutti' is found within the answer.
'the' could be 't' (the is pronounced as a 't' sound in some dialects) and 't' is found in the answer.
This explanation may well be incorrect...
(Other definitions for tutti-frutti that I've seen before include "Type of Italian ice cream" , "Ice cream variety" , "Type of ice-cream" , "Mixed fruit ice cream" .)
