Official Marketing Text:
Hellooo new friend!! Wait... No- NO! Why would you do that? Lights on, lights on! I-I warned you- I WARNED YOU! Bad children must be punished...
Sun and Moon are inseparable, arriving to Youtooz together as a duo plush - one side showing the bright and cheerful Sun, and the other showing the Dark and rule-enforcing Moon. You can't have one without the other, so they made sure they always had each others backs. At 12 inches tall, they're the perfect height to keep watch over you while you sleep or while you're awake! Their real bells jingle just like in the game, so you'll always know when they're nearby and ready for a good hug. Their extra soft hugs are thanks to the patterned minky fabric and premium PP cotton they're made out of, which ensures that every cuddle is a perfect one.
