To draw Christmas Pikachu, start by sketching a circular head with a pointed tip, similar to a Pokémon's head. Then, draw two small ears and two black eyes, with a white highlight in each eye. Next, draw a triangle-shaped nose and a small mouth with a mischievous grin. Add two small ears and a rounded body. Finally, color Pikachu's body in bright, festive colors like red, green, and gold. With a little imagination and creativity, you can create a unique Christmas Pikachu that captures the spirit of the season.
