"Sort of. I do construction. I'm pretty strong." Impa had explained it once, back in Hyrule, that years of using the Golden Gauntlets had left their mark on him, and that's why he was much stronger even without them than an average Hylian, but Link didn't care much why magic worked so long as it did work.
"And when I need to be stronger, I use this." Link reached into a pocket apparently just large enough to fit three fingers and withdrew a mask decorated with a Goron's face. "You weren't with me when I went to Termina. I got these magical masks. I can turn into a Goron with this one, and you know how strong they are."
He put the mask away before he was tempted to put it on and then probably cause a lot of attention to be drawn to him. "And sometimes... well, no, never mind, it's silly."
