all you have to do is get an oddish and evolve it with a type of stone
Gloom and Sunkern.
use a sun stone on a gloom
Get a gloom and give it a sun stone
he evolves into gloom starting at level 21
It evolves Gloom into SUNFLORA. And another Pokemon i cant remember.
To get a bollosom,you have to get a gloom and a stone called "sunstone."Give the sunstone to gloom and it should evolve into a bollosom
It evolves gloom into bellosom. Then it also evolves Sunkern into Sunflora.
There are two ways to evolve a Gloom, you can either evolve it into Vileplume or you can evolve it into Bellossom. To get Vileplume all you need to do is use a leaf stone on it. Likewise to get Bellossom you have to use a stone on Gloom, but this time it is a Sun Stone.
The Leaf Stone may be used on Gloom, (evolving it to Vileplume,) Weepinbell, (evolving it to Victreebel,) and Exeggcute, (evolving it to Exeggutor,) in Pokemon Fire Red.
In all of the Pokemon games Oddish evolves to Gloom when it is level 21, then you can evolve it into Bellossom with the sun stone or Vileplume with the leaf stone.
The sun stone is an item similar to the thunder stone, water stone, fire stone and leaf stone it evolves two pokemon: Gloom and Sunkern.
Gloom is a Grass-Poison type Pokemon.
