Here are some cool things about TDM.
You know that in TDI and TDA you get Gilded Chris/Marshmallow to show that you're safe. In TDM, you get a barf bag filled with peanuts to show that you're safe. The contestants in TDM travel around the world to sing songs of that type so if they go to Egypt they have to sing Egyptain music. I'm not sure about if that last thing I said is true but i'm pretty sure it's right. If they don't sing there out.
The contestants are...

Duncan,
Lindsay
Gwen
Courtney
D.J
Alejandro-new!
Cody
Heather
Harold
Tyler
Leshawna
Bridgette
Sierra-new!
Owen
Izzy
Noah

and I'm pretty sure Ezekiel and Eva come back later in the season.
