How does the sun propel itself on its daily cycle then, if it is less dense than the atmosphere, because it should float? (I assume [dangerous] that it's made of superheated plasma)
I have to admit I came up with the sun's behaviour first, and left the explanation to more thorough speculators like yourself.

I'm sorry about that Erik :~) , I shouldn't speculate so much (It is your invention after all, and I couldn't do any better myself). So, I'll make some amends by giving an explanation
Okay, since you are over-secretive about what's in the pie "
core"
, I can make some assumptions about the volcano, and the "
sun"
.
This is my explanation of the phenomena of the "
sun"
. Ahem....
The volcano contains an extremely hot mixture of some sort of molten material, which, like lava in our world, is very hot but is more dense than the atmosphere so it cannot normally float. The "
core"
of this "
pie"
is, however, very much hotter than our own Earth's and the atmosphere much denser. The core is so hot, in fact, that when a "
hotspot"
of molten material becomes much hotter than the surrounding material, it has enough energy to vaporise the material, and so it becomes a superheated "
blob"
of plasma gas. The movements of the liquids, composed of magnetic material and rock, beneath the surface also generate very strong magnetic fields and so all of it becomes polarised. The plasma gas, pulled by the magnetic field towards the centre volcano, rises very rapidly, and because it is much less dense than the atmosphere, shoots up out of the volcano until it reaches a height where it cannot rise any more as the atmosphere becomes too thin, just like in a lava lamp. The plasma blob stays attractd to the surface of the pie due to gravity, and over the volcano because of the strong magnetic field holding it there. The gas itself is of an extremely high temperature, and so it has enough energy to emit white light and heat to warm the "
pie"
up. This floating ball then floats there until it begins to lose energy, and grow a little dimmer until, it is cool enough to become dense enough to fall back into the volcano. This can only ever happen once a day because the heat loss needs about a day to recover, though sometimes, another "
blob"
may be ejected for a shorter period during the night and cause mass sleeplessness throughout the "
world"
.
I suppose it covers most of it...
Well, not really... Don't say anything about the heat problems because I cannot find a suitable explanation for how the pie doesn't melt, except this, which is nowhere near explanatory enough:
The core is much deeper down than in our own Earth, and that the rocks have a higher specific heat capacity than our own rocks (You need more energy to melt them).
Oh, well, enjoy, and if you can see a mistake or flaw, dispute!
