Sky-Blue Spinies are enemies in Paper Mario: The Thousand-Year Door. They are only found in Pit of 100 Trials (Rogueport) and are summoned by Dark Lakitus. There's not much of a difference between them and a normal Spiny, thrown by regular Lakitus. Only the fact that Sky-Blue Spinies are much stronger. Like a Spiny they can curl into a ball, making themselves protected from attacks for one turn. To jump on them you need the Spike Shield Badge or you will take 1 damage.
