Had to be Red that not only finds a giant Torterra but catches it as well. Anyway this thing is massive, the normal Torterra is only 7'3" I think, I havent looked at its Pokedex in a long time.
While it's true that this is not the size Torterra is supposed to be, it's about the size I wish they would be if they were real and I could have one to keep me company on walks or help me carry the grocery bags. A giant turtle is way cooler than a car.
