Gulu's treasure shop is hidden beneath the forest. It doesn't sell gold or gemstones. The "treasures" here are small, precious things in nature that everyone overlooks and takes for granted: smooth pebbles, beautiful tree bark, dried flower petals, empty snail shells, and intact feathers. Gulu carefully sorts them and lends or gives them to little animals in need, helping everyone solve their little problems. The themes are discovering the beauty in ordinary things, cherishing little treasures, being helpful, and respecting every friend for their differences. The pace is lively, and the colors are soft.
