Daisuke I still need two pokemon.
For you I give you a Sunkern that must always know growth, and can't evolve till after you defeat Jasmine.
Oh, I thought juju gave you a Tangela.
Otherwise...I'll give you a HootHoot that can't evolve or get rid of "Foresight" till level 30.
And a Ledian that you must teach Aerial Ace to if/when you find the TM (In Mt.Mortar, upper cave). But that's a bit too easy...So you can never give this Pokemon a Rare Candy, Stat Boosters, or let it in the Day Care Center.
Can i give you another? if not then you can pick which one.
