Most of the trolls appear to be loving and family-oriented. They live at the land of the Living Rock and are the family to Kristoff, a human who they adopted when he was a child.

Some notable troll characters include Pabie (the troll king), Bulda and Cliff.  When Bulda and the other trolls try to convince Anna to marry Kristoff. Sometimes, they seem crude and a bit intrusive, but their affectionate teasing only endears them to Anna. They consider Kristoff and Sven to be part of their family, and they treat them as such.

• It should be noted that the crystal necklaces each troll wears represent a gender or position in their culture:
  • Male trolls wear blue or green crystals.
  • Female trolls wear pink or red crystals. The female trolls also wear flowers in their hair.
  • Pabbie, Bulda's father, is the only troll to wear yellow crystals, possibly signifying his role as the leader.
    • When they speak, their crystal necklaces lights up as seen in "Fixer Upper".
