Link small, and not stocky either - but he's still pretty strong. Or strong enough, at least.

As Link pulls, and between the two of them they slowly drag the beast, he frowns at Gladio. "High gravity planet?"

(He had a vague knowledge of what gravity was, he knew, although not where he learned about it. But he didn't know enough to understand what Gladio meant when applying that to a planet, or what it meant if you made it...higher?)
