Yi struggles to recreate her violin magic without Everest. As her mom and NaiNai prepare for the grand opening of their family dumpling shop, Yi, Jin, and Peng discover that Yi’s violin has attracted a magical bird-like creature.

While Yi and the crew try to pinpoint how Yi’s magic works, they notice that Everest isn’t looking too hot. In fact, he’s too hot. The crew tries everything to cool him down, even begging their old foe, Burnish, for help.

An earth-shaking rumble signals the arrival of a new creature, but Yi and Jin butt heads, each convinced they’re the better team leader. The crew eventually discovers that the massive Sewer Koi is behind the earthquakes.

With the sudden closing of a local candy shop, NaiNai is busy trying to recreate its famous candied fruit. But after a late-night sugar binge in NaiNai’s stash, Peng starts acting strangely. It turns out that he’s possessed by magical creatures!

On the brink of his highly-anticipated White Coat Ceremony at school, Jin proudly dons his new white doctor’s coat around town, unwittingly drawing the attention of a creature named Morty.

Already stretched thin between responsibilities, Yi discovers one of Morty’s babies still in her building. She attempts to juggle her various responsibilities, but it’s too much and she accidentally “loses” Mini-Morty.

Right before basketball tryouts, Peng learns from NaiNai that it is his “big bad” year on the zodiac calendar – which means bad luck.

A wish-granting toad drops into Yi and the crew’s life just as the dumpling shop is being reviewed by a food magazine writer.

It’s Chinese New Year! With Yi and Jin tied up in their respective CNY festival performances, Peng and a semi-disguised Everest hit the festive streets, eating and enjoying everything in sight.

Yi realizes that Peng and Everest were taken by Nian, the legendary dragon-like creature associated with Chinese New Year – and he’s also taken their other creature friends!
