"A vessel of white, to hold the down."

"Okay, step one." Applejack stated cheerfully. "What next?"

"Hmmm... A feather of blue, to match the sky 'round."

All eyes turned to Rainbow Dash, who fidgeted for just a second, before extending a wing out. She reached her head back there, inspected her feathers, and then singled one out, gripping it in her teeth and plucking it, with only a slight wince and an 'ow' from her lips.

"Thank you, Dash." the unicorn soothed, as the pegasus dropped the feather inside the vase. "Also inside the vase, we need... A stone of fire, from light which grows..."

Rarity levitated a ruby from her saddlepack, the surface gleaming flawlessly. With a smile, she nudged it down into the ceramic vessel, trying to disturb Dash's feather as little as possible.

"And finally, Pinkie. The essence of flower, for which the sun glows!"
