Sabre helps an injured SnowHorn by feeding him an Alpine Root he found.
Alpine Roots are large, beetroot-shaped plants that grow underground in the SnowHorn Wastes and DarkIce Mines. The SnowHorn love to eat them, but are unfortunately unable to dig them up by themselves. The Roots are dark yellow, and have dark, horizontal stripes running along their surface. They grow two leaves above ground which reveals their location. They can be dug up by using Prince Tricky's Find Command.
In DarkIce Mines, Sabre has to find two Alpine Roots for an injured SnowHorn after saving him from a group of SharpClaws. After feeding the Roots to him, he tells Sabre to hop on his back, so they can go smash the main gate, allowing Sabre to continue his journey.
