Actually there is no specific route to get the wardrobe teleporters. They are given out randomly in the game (every 500 plays is what I've heard) which is what makes them somewhat rare. You just have to keep playing and hope you get one or trade with someone.
I'm sorry but they are not at all very rare. You can trade for them by giving buyables because ALOt of people have like 10 sets of them. I know I have 4 sets and someone actually had a 100. - They were trading them in VMK forums -
On topic: I heard you get the teleports before starting a game, like a pop up comes.
yea its not exactly 500 you could get it in 2 tries or 1000 tries its just random but this girl on vmk had this cheat program that let her bring up thousands of games at one time she was reported and banned and the program was made useless
