Grass type.

Touya looked through the five Grass type Pokemon girls.

There was Bulbasaur. She had long, green-dyed hair that matched her scales and the bulb on her back. She had small breasts but a rather large ass.

Chickorita was very cute. She had long black hair, medium sized breasts and a normal sized ass.

Treecko had cropped red hair, and little weight on her, with small breasts and an equally small ass.

Turtwig had yellow shoulder length hair, large breasts and an oversized ass.

Snivy had short black hair, above-average breasts and a small ass.

Touya thought very carefully about the choice he was about to make.
