I’m gonna have to agree with Gig on this one, Celestia had trained him to be a bigger doormat than Coco and Fluttershy together since he was a baby.

Why 5072F in specific? Picked a number, or is that the melting point of something specific? :p
 
(Reinforced Carbon-Carbon, a compound used for the most intensely heated parts of spacecraft heatshields, can take up to 3,632
F. Tungsten has the highest melting point of any element at 6,177*F)

I know the obvious reason is because of screenshots, but it’s weird seeing shots of the library background in these pages…
