Which episode does Stewie become a dancer?

Stewie doesn't become a professional dancer in any specific episode of Family Guy. He does, however, display an unexpected talent for dancing in the following episodes:

* "Road to the Multiverse": Stewie attempts to dance with Brian after being inspired by a musical number.

* "The Giggity Wife": Stewie participates in a dance-off with Brian and Peter.

* "Road to Europe": Stewie and Brian take a dancing class while on a trip to Europe.

* "The Drunken Clam": Stewie shows off his dancing skills at the Drunken Clam.

While these are some examples, Stewie's dancing abilities are not a consistent plotline, and he is more known for his mischievous personality and cunning intellect.
