Danny's parents are botanists; there are various plants in the family. They also keep several rare and endangered plants in the world. These rare plants have been targeted by lawless people. Although only 5 years old, Danny is already very interested in plants and has a lot of knowledge. One day, while his parents were out, little Danny was playing alone in the backyard and accidentally saw a secret entrance. Although worried about danger and monsters in the cave, little Danny still climbed into the cave and secretly covered the entrance. He felt around the dark cave, but his foot slipped and he fell. For a moment, he was afraid, but a sofa-like thing caught him, and he ended up on a long slide. He slid quickly towards a bright place. Finally, when he stopped, he was stunned by what he saw. It was a place filled with big plants. He saw a sign hanging from a tree, which read: Plant Kingdom. His parents had hidden many rare plants from their collection in the plant kingdom. Here he decided to go on an adventure and in the end, was finally saved by his parents and several endangered plants. He became good friends with several small plants in the kingdom.
