Doesn't the Mission Selection screen in the game contradict that picture? I mean, a whole layer made out of energy crystals?!? I think that if Planet U is that large in diameter, it must be immensely dotted with cave systems (which is plausible, given all the different caves in the game) so that its mass is similar to that of Earth's with a vastly different volume. The wiki page on Planet U talks about the different layers (crust, upper mantle, middle mantle, lower mantle, upper core, and inner core). Does anyone know the source of that information? It'd be obvious that the planet is very old and the mantle and much of the core have cooled and hardened to rock. And the wiki also states that the surface has Polar ice caps (with dotted lakes), lakes and rivers of lava, and geysers.
It didn't say the whole layer was made of crystals. They went to that layer in the book; It was rich, but still just lots of rock. I assume the Middle and Lower mantle were combined in the game. And hey, planet sizes in the Bionicle line are even more screwy than that.
I never heard of the surface having polar ice caps... certainly not in any book
