They don't necessarily "get married", but if you connect them they can become friends and eventually make babies.
1. One has to be a male and one a female. They cannot make babies if they are the same gender.
2. To connect press A until you reach the heart icon, on both of your tamas, then press B to select it. Then make sure you select ver. 3 from that menu.
3. They will interact with eachother, become friends, and if they are old enough, eventually fall in love and make a baby. Both your tamas need be at least 5 years old to make babies.
4. To check their friendship progress select the book icon on your tama, select friends, and scroll through until you find the tama you want to check on. Press B to scroll through their stats. If they have 4 hearts, they will be able to make babies.
