That's the one thing foxes like - wee (5)
I believe the answer is:
bingo
'wee' is the definition.
Although both the answer and definition are singular nouns, I cannot understand how they can define each other.
I don't understand the remainder of the clue.
Can you help me to learn more?
(Other definitions for bingo that I've seen before include "Number-calling game" , "Number game" , "game requiring little ability" , "Lotto" , "Voila!" .)
