Bait and switch! Here's a super ball example:

Put a male ball python in with a female ball python during breeding season.

Switch out the female ball with a blood

Trick the male ball into mating with the blood... now it's not necessarily as easy as 1, 2, 3 but that is how you attempt it at least.

Now if only it was this easy in real life, I'd gladly offer myself up to help less fortunate-looking men than myself!
