Not long ago JackalyenMystique asked me whether or not Sir Celestine had a pet; and indeed he does!

Celestine has a pet rock just like his mother Maud. His rock is named Boulder Jr. and was given to him at a young age as a birthday present by none other than Maud herself.
He really adores his pet rock more than most things; other than makeup and Ophelia.
Celestine only discovered on accident that Boulder Jr. was actually a geode rather than some other ordinary boulder. This was discovered when Celestine accidentally tripped on his way to a class Show-and-Tell with Boulder Jr. in tow as his showing item! When he tripped, the precious stone fell and cracked harshly against the pavement, splitting it open and revealing its innards.
Celestine cried in this moment as he sat there with his precious pet split into two pieces. Ophelia later convinced him that it was a good thing; not everyone can tell how beautiful someone or something is on the inside just by looking at their outer appearance.

Boulder Jr. now resides in safety atop Sir Celestine’s makeup table, glittering under all of his lights.
