Okay, go to your local IKEA furniture store. Hide in the wardrobes. When you think someone is walking by, fall out and yell NARNIA IS BETTER THAN IMAGINED and try to get the "victims" to "go to Narnia"
go to walmart....... you'll know what to do when you get there. build a " bedroom" out of all the stuff you find there right in front of the TV displays, most importantly just do stuff that won't get you arrested,
