Abominable And The Invisible City

While her mum and Nai Nai prepare for the grand opening of their family's dumpling shop, Yi, along with Jin and Peng, discover that Yi's violin has attracted a magical, bird-like creature, Fenghuang, who needs their help.

Yi and the crew notice that Everest isn't looking too great; 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 when each is convinced that they're the better team leader; the crew eventually discovers that a massive Sewer Koi is behind the earthquakes.

After a late-night sugar binge from Nai Nai's stash, Peng starts acting strangely; it turns out that he's possessed by magical, sugar-addicted puffball creatures called Minticon.

Jin proudly dons his new doctor's coat around town, unwittingly drawing the attention of a creature named Morty; after a slobbery lick from Morty, Jin turns invisible.

Yi discovers one of Morty's babies still in her building and attempts to juggle her various responsibilities, but it becomes too much and she accidentally "loses" Mini-Morty; Yi enlists help from Jin and Peng.
