He decided to draw Eevee and all the different Pokemon that Eevee evolves into. The Eevee-lutions, if you will.
So, here are his drawings thus far:
This first one is Eevee, the basic form of the Pokemon.
Next is Flareon, which is the fire type Eevee evolution.
And Vaporeon is the water type evolution.
Umbreon is the darkness type evolution of Eevee.
Leafeon is the grass type Eevee.
Finally, we have Jolteon, the electric type evolution of Eevee.
And now you know more about Pokemon than you probably wanted to. But I thought that Connor was doing a really great job with his drawings, so I wanted to post them.
