I'm not entirely sure what the Hidden Falls was, but there was the Crimson 4-Leaf one and, if you would consider this one, an hour long episode right before the second leg of the Chuunin exam... half was a big flashback, in the form of Konohamaru interviewing people about the first arc (Zabuza/Haku).
that is equal to 2 episodes.

sasuke fight against gaara was also 2 episodes.
