Collabooru is a crystal ponification. Her tail, however, is an augmented, non-crystallized but translucent hourglass, representative of this event being an annual one. Her cutie mark is a special fusion of Trixie's and Derpy's, as their names and cutie marks together brand the site — and she is pink and inverted in the colors of the pink tag. ✨
Hourglass is vectored based on a screen of The Cutie Re-Mark Collabooru's hairstyle is reminiscent of Rarity's from The Gift of the Maud Pie
Not tagging with the collaboration tag until the event awards for the 2023 collaboration are finished to avoid any confusion. 👍
