Since Icelandic aerobics champion made Magnus Scheving made LazyTown (Latibær) in Iceland in 2004, there of course had to be an Icelandic dubbed version to market to Icelandic speaking audiences. It aired on TV in 2005, and was released on DVD the same year.
Penguin Productions 900 uploaded this Velkommin til Latabæjar (Welcome to LazyTown) DVD ISO rip to the Internet Archive a while ago and kindly, generously gave me permission to upload all the episodes (Welcome to LazyTown / Velkommin til Latabæjar , Dr. Rottenstein / Glannfinnur læknir, Sports Day / Ípróttadagur & Super Hero for a Day / Hetja í einn dag) individually to YouTube. 
The DVD has English and Icelandic subtitles, but I uploaded the videos without any subtitles. I have only uploaded two episodes as called in the Icelandic language, ‘Velkommin til Latabæjar’ & ‘Glannfinnur Læknir’.
I will probably upload the rest soon, but who knows? Credits are sped up by me to be ten seconds long, making 24 minutes straight of video time.
