Humorous joke: What episode is dwarf?

I don't know if the comic that the landlord is looking for is sparkling. Season 02 episode 09, the dwarf is trapped by a bubble. The play mainly tells the crazy and fantastic adventure stories of the magic elves Liangliang, Jingjing and their best human friend Leah. Whenever Leah is in trouble, she will say a special spell, rub the fairy bottle pendant and summon her secret fairy to shine. Two sisters took their special pets Rahu Nahar (a Bengal tiger cub) and Tara (a lovely gibbon) to fly from their fairy tale world to the world on a magic carpet, and helped Leah tide over the difficulties by satisfying her three wishes!
