Design a festive axolotl crocodile hybrid with vibrant red and green hues. His rough, textured body glows with bioluminescence, especially around his white, flaring gills. His large, round eyes sparkle like stars, and his expression is joyful and playful. his small, webbed feet are perfect for swimming, and his spiked tail is long and graceful. This creature should radiate warmth and festive charm, adding a touch of magic to the underwater Christmas adventure. #ChristmasAdventure#
