Oh hey, Cloud! You're just in time for our favorite game—Whack-a-Box! You want in? It's super fun!
Sarah is a minor character in Final Fantasy VII Remake. She is a young girl living in the Sector 5 Slums. She hangs out at the children's hideout with her peers, and is scared of monsters and worried about the recent turmoil that has been taking place in the city. She is playful and likes Aerith Gainsborough.
After Cloud helps the children out and defeats the "king toad" wandering in the kids' hideout, Sarah will let Cloud play the Whack-a-Box minigame where Cloud must accumulate a score by destroying boxes within a time limit; scoring 30,000+ earns the grand prize, but Sarah always gives Cloud a Moogle Coin as a participation trophy. Playing Whack-a-Box is thus a good way to earn coins to trade with Moggie.
