All you need to do it is evolve it with a Fire Stone. No leveling up is required, but recommended.
You can find growlithe in the patch right outside of the town with the big Pokemon graveyard. It may take a long time for you to find one though, it took me half an hour.
magnemite evolves at level 30 into a magneton. Resources- I'm currently playing the game
Staryu can evolve into Starmie at any level, as long it is exposed to a Water Stone.
No you cant sense crystal is a different reegion then pearl,diamond and platinum.
When you say 'long tongue' it makes me think of Lickitung (no.108), however it first appeared in Pokemon Red, Blue and Yellow not Crystal.
He will evolve into Garchomp at level 48. It takes a long time but he has very powerful movies and is really strong.
It needs max loyalty with its trainer you can evolve togepi in one level has long as its happiness with its trainer is at the max.
It'll evolve at level 40. It may take awhile.
just give the right stone to it and it will evolve straight away e.g. eevee+firestone =flareon
I've heard one of them is a lickitung because he wants to see a Pokemon with a long tongue. Hope this helps!!
You have to level up feebas with maximum beauty, which can be done by giving it poffins. It can evolve at any level as long as it has maximum beauty.
It depends in how many times you use it in battle, if you use him allot and he levels up soon he will evolve.
