Celestia rushed back into Twilight's room. "Princess Twilight, you have to help!" The look on her face said it all.

"Some kind of monster invading? Need to blast it with magic?"

Celestia nodded. "It's plunderseed vines."

"No problem. Let's go."

Together, they rushed back out to where Celestia had been attacked, finding the withered vine still there.

"I see." Twilight's horn flared. "Now, we'll just do a quick tracing spell..." A tendril of light connected her to the vine, and her mind followed the route it had taken all the way from Canterlot Castle, through Ponyville, deep inside the Everfree Forest, and... "It's coming from some huge, glowing tree deep in the Everfree Forest, near the old castle."

Celestia nodded. "The Tree of Harmony. We must save it!"

At that moment, Princess Luna burst in through the door. She held a torn black vine in her teeth and spat it out onto the floor. "Sister! Plunderseed vines are attacking. They attempted to take me whilst I slept!"

"Already on it," Twilight said. "Come on, we've got to save the Tree of Harmony from them!"

With a multicolored flash, all three of them teleported there.

The tree was totally covered in gooey vines, and the first experimental blasts of magic were none too effective. The vines had an impressive resistance. Of course, they couldn't withstand the combined might of three princesses, though. Together, their magic quickly burned away the vines, following them all the way to their roots and completely exterminating them.

Twilight grinned. "All in a day's work."
