Pikachu – Mouse or Rat?
Oh! I did not know Pikachu was a rat!
In Wikipedia, about Pikachu, it is written: “Pikachu are designed as short, stocky, mouse Pokémon that have short, yellow fur with brown markings covering their backs and parts of their tails“.
But happily, like so many pictures circulating on the net, it looks like the yellow color has been added with Photoshop.
