There is no such thing as a "pikablu".
This was a popular English name for the Pokemon called "Marill" before the release of the second Pokemon movie outside of Japan.
Marill (depending on which game) can be found in the wild.
Depending on the game, Marill can also be easily caught using an Action Replay to help players.
