En-Uk's Spaced-Out, Toilet-Trained, Conference-Attending Horse?

My eleven-year-old son, En-Uk, is still posting his art over at his art blog, and he recently posted this thing that he calls "Space Craft":


About this image, he wrote:

This drawing is called "Space Craft." I made this drawing because I like space crafts. Bye.

I had a slight difference of opinion:

Next time, show the entire spacecraft, not just the toilet!

But my friend Kevin Kim offered an entirely different perspective:

Horse angrily pounds conference table to get everyone's attention.

Interesting. I can see that. And as I recall, a horse's ass once did that with his own shoe in the UN. Anyway, Kevin later sent the image below:


And he wrote this message by way of explanation:

Attached is a gift for En-Uk, done up roughly in his current drawing style, in which I've fleshed out my vision of the horse pounding angrily on the conference table. The rectangle in the picture surrounds En-Uk's original artwork, which inspired the rest.

I think that it's great! Thanks, Kevin, from En-Uk and me.
