Pineco levels up just the same as all other pokemon, so... If it's at a low level, either go train it on an early route or make it hold an experience share. The day care is also an option if you're feeling lazy.
In Pokémon Conquest, after you have captured a wild Pineco whiole in the Chrysalia Kingdom then you will be able to evolve it once its defense is at least at the level of 73 however once its defense is at least 73 then Pineco will end up evolving into its next stage which is known as Forretress.
Level 50.
you can get to level 100 but no higher

level 20
Lvl 31
Outside of Mt.Silver.
Forretress cannot be caught in the wild; you must level up a Pineco to lv. 31 to evolve it. Pineco can occasionally be found by Headbutting trees.

Use headbutt on a tree
pineco,aipom
Get a Pineco from headbutting a tree, and then evolve it into a Fortress.
he evolves at lev.31
teach headbut to a Pokemon (anyone can learn it), then headbut the tree on route 31 that is by itself. pineco will then appear around lv 4.
im pretty sure you can find one in the forest by azalea town
Pineco's are quite common throughout Johto. Just catch one, level up up to lvl 31 and you have a Pokemon only weak to fire.
fly to victory road and go down 3 flights of stairs and the tree next to the rock will have a pineco i got mine on my second go
