Zony and Yony, the six year old twins from Taiwan, appeared for the second time on The Ellen DeGeneres Show which aired Tuesday.

The twins danced to the popular Justin Bieber song “Baby”, impressing the audience once more.

The Taiwanese sisters wore denim vests, colorful stockings, blue helmets and purple tutus while performing a new dance number choreographed by Twitch and a guest DJ.

Ellen was appalled with the performance of the twins, making her give them Hello Kitty presents including two bicycles.

In the pre-performance interview with the twins, DeGeneres asked what their favorite things in the US were, and they said they have been into pizza and ice cream.

Ellen also asked the twins if they have watched American TV shows. The twins’ answer drew laughter from the audience when they said they have watched the “Ellen Show”.

The American comedian and TV host also said during the show that she has been trying to practice on her Mandarin lately.

The video of the twins performing on Ellen was uploaded on YouTube where it garnered 170,000 views within 14 hours of its posting. The clip showed the girls learning new dance routines from Twitch and how much they enjoyed their practice. The twins also taught Twitch how to say “bee” in Mandarin.

The twins were first seen in a YouTube video posted in February. Zony and Yony danced to Bar Bar Bar from South Korea’s Crayon Pop. The video went viral on the social media video sharing platform.

Since then, the video has received more than 2.1 million views on YouTube. This has led Ellen to take notice of the girls, eventually inviting them to her show. The twins have also appeared in numerous TV shows in Taiwan.
