The Robonic Stooges was an animated series created by Hanna-Barbara, that aired from 1977 to 1978. The show revolves around The Three Stooges (Moe Howard, Larry Fine, and Curly Howard), who are now robotic crimefighting superheroes. The entire series can be found online via full episodes on pirate websites and clips on YouTube, but one of the 32 episodes, "Curly of the Apes", is incomplete.
The premise revolves around The Robonic Stooges trying to stop an ivory poacher named "Tricker Mortis", who steals entire elephants. At one point in the episode, Curly ends up encountering some apes, hence the title. It’s not known how the episode ends, as the episode is not fully available.
Only the first two minutes of the episode is available online. The Robonic Stooges never had a home media release, but the rest of the series is fully available from its reruns on Boomerang, which are viewable on the internet.
