>>39988977It's a reference to both an episode from the Orange Islands arc, and a special attack animation from Pokemon Stadium on N64. Puka was an elderly surfing Pikachu with blue eyes who could feel ocean waves coming with a psychic-like sixth sense, and in Pokemon Stadium if you unlocked surfing Pikachu but evolved it into Raichu, instead of summoning a surfboard it would jump onto its tail to surf the wave instead.
You would know all this if you weren't a fucking zoomer, boy.
