World of Giants is the 15th episode of the series and the first episode of Season 2.
Plot
When Sparx says that Tolomac 3 is just another piece of rock floating in space, he couldn't be more wrong. It turns out that there's an entire kingdom of giants living there, and they've mistaken the Super Robot for one of their own. Sparx decides to take advantage of the situation and pose as a knight, but the Super Robot is losing power, and unless the team can find the nearby energy source, they'll be stuck there for good! But there's one who doesn't want them to leave: he wants to get rid of this square-headed knight himself.
