Yang might want you to bring him some turkeys in Spelunky 2, but these noble creatures have other benefits. You can tame a turkey and ride it like a mount, although there are some risks.
The advantage of riding a turkey is that you will be able to do a double jump. You'll still be able to attack as well, but instead of swinging your whip, the turkey will strike with that colossal neck, facing any enemy that comes your way.
How to tame a turkey
To tame a turkey, just jump on its back. The turkey will panic and try to sneak around the screen, so you want to do it somewhere safe. Find a nice place without traps, creatures or surprises and transport the turkey there. A perfect spot is a single block hole, because the turkey cannot escape it.
Let go of the turkey, then jump onto its back, and after a short while the turkey will become tame and you will see love hearts coming out of it. Now the turkey is your friend and you can ride it on the screen. If you get knocked down while taking damage, you can just jump again.
How to do a double jump
When you are on a turkey you can double jump just by pressing the A button twice. This is a useful way to safely take long drops, make difficult jumps, and even evade some enemies or traps.
The last thing you need to know about turkeys is that if you are in poor health you can use a bomb to kill them and then scoop up the cooked turkey meat. It will give you back a heart, but don't let Yang see you doing this or he will come after you with a vengeance.
