3rd Gen PokeBlock Master

Well, the pokeblock man finally came.
And, its so easy to get gold blocks.
But there is to get high level blocks by only pressing one button.
All you need to do is get your first button press right.
Then he will do all the work.
The rpm will reach like 150 at least.
My highest is 158.(some wierd number)
It will go up by ten until 90. Then go up by 3's
You get so many high level blocks.
My whole case is like full of gold blocks.

Who is this pokeblock master?
Is he one of those rare TV events like the Lilycove rooftop sales?

Yes, he is a rare event broadcasted on TV.

Is there any special way to make him appear??? Like fullfilling some obligation, or requirement??

I'm not sure.
I don't think so.
Though you might need to beat the elite four.
Idk
I saw it on the TV randomly.
So always check the TV.
