Sitron

Sitron is a minor character from the 2013 animated film Frozen. He is a Fjord horse, which is native to Norway, where the film takes place. He belongs to Prince Hans, and accompanies him to the kingdom of Arendelle for Queen Elsa's coronation.

Physical Appearance
Sitron is a Fjord horse with a round, strong build. Fjords are solidly built, though not as solid as a large draft, they are a draft type horse. He is dun-colored, and has a mane of black and off-white. He looks similar to Anna's horse, though her's is a paler gray color with a white-and-black mane.

Frozen
Sitron first appears when Anna knocks into him on the docks after "For the First Time in Forever". After knocking into him, Anna falls into a boat, but Hans and Sitron keep it from falling into the fjord. Hans dismounts Sitron to help Anna and introduce himself. Upon hearing Anna announce herself as a princess, Hans and Sitron both bow, tipping the boat. Sitron notices this, then pushes the boat back upright, causing Hans and Anna to fall over. Fortunately, the boat lands on water, allowing the two royals to introduce themselves. When the coronation bell rings, Anna leaves as Hans watches, but Sitron removes his hoof off the boat to wave to Anna, causing Hans to fall in the water.

Later in the film, during the capture of Elsa, Sitron serves as Hans' mount to the troops marching to Elsa's ice palace, and accompanies his master back to Arendelle.

It is unknown what happens to Sitron when Hans is arrested and sent back to the Southern Isles. However, it is presumed that Sitron was also taken back to the Isles.
