Toz could sense that the cats were handling the jellyfish on the other parts of the island just fine. Relieved, he decided to help Hods and Stitches. Not for their sake but because he also wanted the boats intact. And because the void magic spread by the jellyfish was starting to wear on the island.
Although Toz and Nil had reinforced the trees and the island by filling it out with constructs of metal magic, the void magic's erosion was beginning to dissolve the mana and weaken the island. If Toz allowed the jellyfish to continue, he would put the island and all of their lives at risk.
Since he couldn't rely on the cats or the two pirates helping him, Toz was prepared to fight off the jellyfish alone. Thankfully he had access to an assortment of elements that could fulfill various purposes. But he couldn't use them as deftly as the cats could, so he was forced to improvise.
