hey, i think i may know your problem.

1st of all i didn't have anything to do with the picture on the wall and still caught rotom or whatever it is called.

the TV is how u get it but it must be at night time. otherwise he will not be there.

then it will say there is a pokemon in it and choose yes to thump TV or whatever.

hope i've helped.

i'm also interested in trading with you if u want to help complete our pokedex's etc.

my hotmail is slayza_notherone@hotmail.com.

hope I helped.
