What Shape Do You Think The Massivecraft "planet" Would Be?

Silly, the sun doesn't spin around it. The sun is a great fireball spit out by the Very Huge Dragon in the East. It arches across the sky and gets extinguished by the time it reaches the other side.

And that must mean the moon is a great ball of ice.. thrown by a sea serpent? Yes, that's it. And it melts by the time it crosses to the other side.

-takes out sword bow and crapy armor- Were is that dragon exactly? maybe i can solve his "firebreathing sickness" so he doesn't ruin my theory
 
I think cube is still a good idea.
I mean... The massivecraft continents aren't infinite are they?
So, that would mean it could be not infinite... Right?
(Please tell me if this is stupid. I feel stupid)
