@Avi In mathematics (more specifically in the variety of "abstract nonsense" known as category theory), a co-X is like an X but "with arrows reversed": if X involves functions from A to B, co-X involves functions from B to A, etc. So a co-bee would do all the same things as a bee, but backwards.

I'm sure you can make a great puzzle out of this if you think hard enough; unfortunately, I happen to be too busy nowadays to do so :(

This puzzle is part of the Monthly Topic Challenge #6: Is it really that [time] again?. I was visiting my grandfathers workshop one day, when he received a call and had to run out for a bit. He told me to sit down and relax and he’d be back any minute. I sat down and noticed a sudoku puzzle that...

ha, the c4 is the literal word STRING making its second letter P (appearance's second), giving SPRING = origin
