How a crocodile proceeds? (3,2,3)
I believe the answer is:
two by two
If this is the answer I cannot explain how the clue works.
Can you help me to learn more?
(Other definitions for two by two that I've seen before include "In pairs" , "How the crocodile walks" , "Animals entered Noah's Ark in this order" , "Arithmetic progress of animals into Noah's Ark" .)
