What is the first thing that comes to mind when one spots an unopened box?

What is inside it? Is it a gift? Is it a puppy? Is it a spawn of Cthulhu? Questions will no doubt flood the conscious mind when an unopened box lies in front of you. Waiting patiently for you to prepare to delve into its contents.

Bert is one of those people. Curious questions and sceptical theories filled his mind when he discovered a box lying in wait in front of his doorsteps. Just what on Earth was inside that box?

Whatever he thought it was, it definitely wasn't a pony.

He found a pony in a box.

And he has no idea on what to do next.
