I’m guessing this carving is a work in progress. I’m not certain what it’s going to become… Though based on the location and the way it looks, I do have one idea.
It might be a dragon’s egg. In which case maybe it is finished!! Okay, I’m sure even if that is what it is, they’re probably going to do a bit more with it.
I have good reason for thinking it is going to be a dragon’s egg. The reason being that this is right next to a play park, and the park’s name translates to “Dragon Park”. Plus, just to the right and a bit in front of this there is a long wall with a dragon mural. A dragon egg would be quite fitting in that case, don’t you think?
