Summoning Epona/Hawk by:Kafei
This is something different in Twilight Princess,
instead of having an ocarina to call upon epona, you'll
have to find a special spot of grass or reed in order to summon
Epona or Hawk this time. The differences between the grass are very
easy to spot. First off, in order to summon epona you must
pick up the horse-shoe shaped grass to use it. Second, in order to
summon a hawk, the grass will be shaped like-wise. You can
use the hawk to retreat hard to reach items, for example the baby
carriage in the begining of Twilight Princess. Now remember,

To Summon Epona- Horse-shoe or horse shaped grass/reed.
To Summon a Hawk- Hawk shaped grass/reed.
