Skyland Season 1 Episode 11 Red Rock People

After receiving a radio distress call from their father, Mahad and Lena take off to find its source. Also following the transmission is Oslo, and after a brief dogfight in the air, all three crash land on a mysterious deserted block. Due to their situation and an injury that has rendered Oslo powerless (for the time being), the three start to look for the source of the call. While searching they come across an invisible monster that threatens all of them. It seems this block was formerly a rebel hideout, and before it was deserted, this creature was created to protect the secrets left there. It's up to Mahad and Lena to track down their father's transmission, defeat the mysterious creature and stop Oslo from obtaining the rebel coordinates.
