You can see all the pokemon in the Unova dex but, in order to get the permit, you have to CATCH all the pokemon in the Unova dex. I found that out the hard way when I showed Professor Juniper my pokedex in Nuuvema Town. I had 299 seen but she wouldn't give me the permit for Nature Preserve until I had caught all the Unova pokemon which included Tepig (neither Hugh nor I had one, sadly enough).
Official Cresselia of B/W2 Boards; Official Darkrai of PMD3 Board When will there be an official Cresselia event? When will GF official release Meloetta in the US?
If all you needed was Tepig, you would have had both an Emboar and a Ditto. --- Pokemon White 2 FC: 3010 5906 4214 3DS FC: 4511-0471-8035
