So many good entries omg. Here's mine.
Title: The best photograph
[spoiler]
Description:
Santa stepped away from the camera, smiling ear to ear. “Everyone ready?” he asked, looking back at his companions.
“Just about,” Tim said, stretching to put the last of the lights around the tree as Donner the Trevenant, always helpful, twisted the tree into a more manageable position. Blitzen the Dragonite stepped in to assist as well, allowing Tim to lean against his leg to steady himself.
Santa nodded. “Dasher, Dancer! Get down here,” the snow-bearded man called, and his always-loyal Pelipper and Togekiss glided down from the clouds to hover near the tree.
“Now where’s Vixen?” Tim asked, still struggling with the lights.
Santa turned in time to see the mischievous Jigglypuff grabbing at the camera.
“Oh no,” Santa said. Dasher laughed loudly, flying circles over the scene, while Dancer swooped in to help.
Comet the Ampharos, excited by the commotion, let loose a jolt of electricity that alighted the tree and only added to the confusion. Santa reached toward the camera and the pink Pokémon—
There was a distinct click as a button on the camera was pressed.
Later, Santa would look at the photograph hanging in its frame, and think of it as the best they'd ever taken.
