What episode is the guest appearance of the little devil and fairy Kun in Barabara?

Balabala's little demon, the little fairy Kun, made a guest appearance in the second episode. Episode 2: In the cartoon, Kun plays Du Yufeng, a seven-year-old student. When Kun was a child, he had big eyes and a tall nose. The whole facial features are exquisite, but the face looks a little fleshy. I have to say that Kun was also very cute at that time. KUN,1born in Wenzhou, Zhejiang on August 2, 1998, is a male singer, original music producer and actor in China.
