Sappy was born in a small and cloudy village of Micro seals, where they were forced to live due to the tyranny of the Bad King. Despite the dreariness of their surroundings, Sappy's spirit was as bright as the yellow bomber body they wore. With their rounded eyes and red beanie perched on their head, Sappy stood out among the other Micro seals with their unique appearance.
Growing up in a world where they were often overlooked and underestimated, Sappy learned to be resourceful and resilient. They excelled in their studies at the tiny schoolhouse, always eager to learn and grow despite their limited surroundings.
