The short answer is: of the original Slugterra series.
But if you want to dig deeper (pun intended), the breakdown gets a little more specific. Between the main series, the "jump" to a new network, and the movie length specials, the total count changes depending on how you count them.
| Category | Episode Count | | :--- | :--- | | | 39 | | Ghoul from Beyond (Mini-series) | +5 | | Slugterra: Reloaded | +22 | | Total (Standard Definition) | 66 Episodes | | Plus the 4 Specials/Movies | (Extra runtime, not usually counted in episode #) |
If you grew up watching Eli Shane duel it out with the Cavern dwelling slugs, or if you’re just discovering this hidden gem, you’ve probably asked one simple question: "How many episodes of Slugterra are there?"
