Episode Title:
Jiggles.
Episode Description:
Kowalski creates a living cube of green gelatinous matter after a night of working in his lab, which soon develops a taste for fruit and a hatred of fish. When the cube, which Kowalski names "Jiggles", begins to increase in size, the other penguins begin to get concerned, but Kowalski continues trying to bond with the material, including after it breaks out of the HQ. A mission by the penguins to then recapture Jiggles ultimately fails when Julien and Kowalski wind up being consumed by it, but they are later expelled from it when Julien reaches down Kowalski's throat to retrieve a fish Kowalski had eaten for lunch to provoke the monstrous mass to release them. In the end, Kowalski uses his shrink ray to reduce Jiggles, but unbeknownst to the others, he keeps the miniaturized version.
