La Cucaracha

La Cucaracha is a song sung by Cosmo in the episode The Switch Glitch. Trying to anticipate Timmy's next wish, he assumes it will be a dance number and breaks out in song while magically poofing into a costume. The vocals were performed by Daran Norris, Cosmo's voice actor.

Lyrics
La cucaracha, La cucaracha!
