Turtwig is the fourth papercraft released at the official pokemon site. A Turtwig is a Grass-type Pokémon and comes with the ability Overgrow, which increases the power of Grass-type attacks by 50% once the Pokémon has less than one-third of its maximum HP. It evolves into Grotle at Level 18, and then again into Torterra at Level 32.Pokemon Papercraft
