- "Russell's losing his quills. Blythe's locked herself in her room with some mysterious illness. It's all too horrible for words!"
- —Zoe Trent
The Hedgehog in the Plastic Bubble is the twenty-third episode of the second season of Littlest Pet Shop and the forty-ninth episode overall.
Both Russell and Blythe find themselves in isolation due to real, but mostly imagined circumstances.
Blythe is busy putting on her shirt, while talking to Youngmee about the Fergus & Annabelle book. While listening to the Prince Kissies theme song, she realizes she has three red blotches on her head. She searches it up on the Internet, only to find out that it's called "Geri-Beri".
Meanwhile, Russell is wearing a mask, asking if he is close? The other pets giggle, when suddenly Zoe and Minka come in, alarmed about Blythe's Geri-Beri. Zoe expresses herself by "dancing". The pets giggle some more (not about the Geri-Beri, about Russell), but Russell suddenly bumps into Penny Ling, causing her to get stuck by a quill. Minka pulls it out and adds it to her collection.
