In the novel " Fox Demon Little Matchmaker " and its derivative works, Tu Tu was a Jade Rabbit Spirit who had cultivated for a thousand years, and Tushan Yaya's servant. Tu Tu was originally the younger sister of the three sisters. Because of her low magic power, she had always lived in the shadows of her two sisters, so she had developed a timid personality. Before she lost her memory, Tu Tu was responsible for guarding the Tree of Bitter Emotions. Later, Tushan Reddie erased her memory and became Tushan Yaya's servant.
After Tushan Reddie erased Tu Tu's memory, Tu Tu's magic power was sealed, and she could only exist in the form of a rabbit. In order to train Tu Tu, Tushan Yaya had locked him and little coconut under the tree, letting them bear the power of the tree. Under the tree, Tu Tu felt its power and gradually recovered her memories. In order to repay Tushan Yaya for saving his life, Tu Tu decided to follow her and become her servant.
Tu Tu was timid, but he was very loyal to Tushan Yaya. While Tushan Yaya was cultivating, Tu Tu was in charge of guarding Tushan and ensuring its safety. Tu Tu had also played an important role in the reincarnation of Mud Mountain Reddie and Dongfang Yueyue. He helped Bai Yueyu and Tushan Susu find the Bitter Affection Tree and complete the ritual.
