Daring Do and the Cave of Skulls

Daring Do stormed into Celestia's room, whooping, "yay", and told her the good news. Soon, there was a ceremony!

Celestia, Luna, Cadance, and Twilight were all in gowns, with an audience. Daring Do, with the dead head above hers, walked down the middle of the room. "Today, I am proud to say..." Celestia began. "that THIS... is BACK!" She threw it into the air, casting a spell, and big rainbows burst throughout the room and out the windows. Everypony smiled, the rainbow spreading across Equestria. The Appleloosans cheered... The Manehattanites clapped... and the Ponyvillians threw a party. "Daring Do, here, has gone through the Cave of Skulls, Tartarus, gotten past Tirek, and returned with THIS!"

And you know what? That skull came back to life. The rest of its body came together... still, no one could identify it... or name that creature. But whatever it was, ponies called that particular one, in honour of Daring Do: DAREDEVIL!
