Huh?

[[Kingdra]]

It says on the Serebii site that if I beat Mt. Battle I get a Johto Starter but, I just beat it and I didn't get one.

 

[Fox O' Donnel]

did you do it from 1 to 100 without stopping?

 

[[Kingdra]]

Oh you can't stop?

 

[ShinyManafi]

You can't switch pokemon using the PC, all you do is save, and you can't leave either.

 

[King Sky]

Really? And how many Johto Pokemon can you get?

 

[mrrrrrrr KENNEDY]

just the three starters

 

[Dragon56]

With blast burn or frenzy plant or hydrocannon.
(I do hope people can guess which gets which)

 

[Hejiru]

there is already like 700 theards on this already.
