Tumblabrush, the stubborn pokemon. Grass.
Tumblabrush are obliviously obnoxious weeds. They use their large appendages to invade farmers land and plant themselves among their crops. If farmers do not remove the tumblabrush before they evolve, they'll have a much bigger problem.
Tumblaprick, the prickly pokemon. Grass/flying.
When a tumblabrush evolves, it kills nearby plants and becomes a tumblaprick. This light pokemon let's itself be carried by the breeze and spread its seeds, which attract tumblabrush and encourage them to evolve there. They travel in large clusters.
Scorchiweed, the destructive pokemon. Fire/flying
When exposed to a Firestone or a fire pokemon, a tumblapricks dry branches ignite into a Scorchiweed. These pokemon are highly aggressive, and actively attack anything flammable, including tumblaprick and forcing clusters of Tumblaprick to evolve into Scorchiweed and further the problem.
Im taking all constructive criticism on the concept. Im not a big artist so I put effort into the art but its not perfect, that's just not my strong suit.
