LazyTown Extra is a spin-off of the awesome TV show, LazyTown, also created by Magnus Scheving. It aired in 2008, a year after the original series ended. And...it rather sucks.
Well, it's just hard to watch through an episode. The segments with Stephanie and the other dancers are rather cringy, and the parts with Ziggy (who has a different voice) interacting with real children are hard to watch.
The only good segment is the one with Stingy and the Mayor. And maybe the Sportacus scenes.
I honestly didn't watch a lot of it.
