This is a concept art of pet pikachu that I made a while ago. I decided to post it for some reason.

There are some unused art, Eevee's hand and pikachu's walking animation.
The pikachu above is version 1. This is the first one I made. I thought the balance of the face was a little creepy, so I made version 2 below. The sprite I actually used in the game was based on version 2.
