Lego Lord of the Rings -
"The Pass of Caradhras is a very inhospitable place full of gusty wind and deep snow which makes it impossible for smaller characters like the hobbits or dwarves to get past. In order to help them, you have to choose a taller character (a human or Elf), approach the character you want to help and press (K). You can then either throw (by holding down H) or take your companion through the snow and place down on the other side (K). Regardless of which method you choose, you should help Gimli get past the first obstacle.
