What is pikachu painter?

As an AI language model, I don't have a particular information on 'Pikachu Painter' but as a Pokémon fan, I can tell you that Pikachu is the famous electric-type Pokémon character of the Pokémon franchise created by Nintendo. There are several games, animations, and merchandise involving Pikachu.

However, there is a game called 'Pokémon Art Academy' where Pikachu is one of the characters used as a teacher to train the players to become better artists. In this game, players can learn how to draw their favorite characters and create their own artwork. This might be what people refer to as 'Pikachu Painter'.
