Players who chose Turtwig as their starter in Pokemon Brilliant Diamond and Pokemon Shining Pearl may want to find ways to raise its firepower. Certain items in the Pokemon world can affect a Pokemon's stats in battle, while others can restore health/status effects or raise the power of moves. An item that trainers can get is the Miracle Seed, which boosts the damage of Grass-type moves. By equipping this on Turtwig, or any other Grass-type Pokemon, its damage output from Grass-type moves will increase a little in battle.
