Once upon a time, Regret Cat found a mysterious shiny button in his backyard at noon. Curiosity tingled his whiskers, so he pawed at it playfully. Zap! Regret Cat was in a world made of giant marshmallows by evening. "Wow, tasty!" he thought, munching happily. But the ground turned sticky, trapping his paws as the sun set. Yikes! He saw a marshmallow-man marching towards him. "Help!" yelped Regret Cat, wiggling free just as a glowing portal shimmered open under the twinkling stars. With marshmallows clinging like trophies, Regret Cat jumped through, flopping back in his yard as the night deepened. Phew! Now he regrets the marshmallow mess everywhere.
