One is a cow and the other is the deer (you). Find the cows in or near the basketball court (where the big black and white cow is), kill them and drag one with LT and drop him off on the red button. Then step on the deer one and metal deer will spawn. Jump in and achievement earned.

You need to ride the cow over to the little island with 3 buttons. Put the cow on the middle button and step on the third and the metal deer will get delivered. Ride it by pressing Y

Achievement Walkthrough:

You will need to combine this with God Disguised as a Cow (30G). After riding a cow, fly it over to the small island with the airplane landing strip. You will notice two unpushed red buttons, one requires a cow and the other requires a deer. Place the cow on its designated button and step on yours to spawn in the Metal Deer. This can be very helpful for the DOGGO boss fight (Town Musicians of Bremen (70G)).
