The Bridge to Caballee is the 19th episode of Season 2 and 37th overall episode as well as the series finale of Dora and Friends: Into the City!. It is also the final episode of the Dora the Explorer franchise (unless one counts the US airings of Season 8 episodes in 2019 by the honor of Dora and the Lost City of Gold.)
The plot of this episode is technically a reference to the Hanna-Barbera animated series "Wildfire" which aired on CBS, Nickelodeon's sister network, in 1986.
