Captive tortoises have been known to live for about one hundred and fifty years. Most ponies are lucky to live past eighty. Rainbow Dash was not Tank's first pony, nor will she be his last. The stoic tortoise doesn't have much choice but to live with it, though, and enjoy his time with each of his friends as much as he can.

Princess Luna is ready to take on her role as Princess of the Night once again upon the night of the winter solstice. She remains unhappy, though, for her subjects don't seem interested in what the night sky has to offer. Twilight Sparkle must take it upon herself to prove to the princess just how much Equestria loves the stars, and make this the best winter solstice ever.
