I can barely remember a show I watched on Netflix in its early days (2011-13ish). I remember the show being about how a couple of kids would go into a shed in their backyard and there was a trapdoor with goblins in it. During the theme song, it would show the kids going into the shed, opening the trapdoor, going through underground tunnels, and sneaking around the goblin town/village/city. (They might cause something to explode or something and that leads to the title card, but I'm pretty shaky on that.) I think the goblins were hostile or didn't like the kids, but there might have been a couple friendly ones that helped them (or the goblins weren't mean?).
TLDR: Animated show where kids go into a trapdoor with a goblin city in it.
I don't remember much else, any questions or suggestions would be greatly appreciated!
