Why it belongs. Cozy nap after soaking in tropical vibes. OOYAMA’s delightfully goofy, round Pikachu has flopped onto its back in the warm sand, cheeks flushed and eyes shut, while a little sailboat drifts by. Look closely by the palm tree: a Weedle is peeking out at the sleeper. Even its attack, Tropical Vibes, puts it to sleep.
