raise its IQ by giving it gummies i think level five in stars is when he can evolve
if you use it, it will raise your level up
Golden Seeds raise the level of the pokemon that eats it by 5.
same as in any other game you use a moonstone
You give it items like carbos,zinc,iron,calicium.Only two of them raise attack and defense.
Stock up on plenty of Reviver seeds or alternatively go to other dungeons and fight to raise your level.
you play more games and you raise your medal level
You just have to raise your heroe's level
pichu cannot evolve you have to raise its happiness items that are approved for its happiness are soothe bells and luxury balls etc
You need to raise its friendship not raise its level.
you feed them gummis
you can't raise them to level 999 because the maximum is level 100 and anyway if a Pokemon could reach to level 999 I'm not saying they can, it will take a long time to raise them
