Twilight made new potions with Princess Celestia every day, but this time, that all changed...
As usual, the two of them were making potions. "Now we need to add a tiny dip of Griffon Feathers!" Twilight squeaked.
"Okay, I'll go get the tools." Princess Celestia offered. "I'll come too, I think I dropped one of my notes." They both walked off.
A mysterious shadow came into the castle when they were gone, the shadow switched the potions up and vanished. The two came back to the gadget table. Twilight carefully dipped some Griffon Feathers into a chemical, "Now we need the most important potion
of all.." Twilight said. Princess Celestia grabbed the potion, "One mistake, and it's all over.." Twilight warned. That's where it all went wrong. The mysterious shadow replaced the important potion with Snake Eyes Toxic. It slowly poured into the cup, it exploded. "Whoa! That's not what is supposed to happen." Twilight said as she checked the book again. "Perhaps they missed something." Princess Celestia answered. "I guess so.." Twilight felt concerned about this weird happening. The Griffon Feathers had burnt up from the explosion, but they thought it was safe to offer free samples of the magic to the ponies. The unicorns bought all they could, and they all used it at the same time. A giant explosion came from houses of Ponyville, and that, is where the story kicks in.
