The two guys after Elsa try to hurt her multiple times
Elsa impales a man with icicles, pinning him to a wall. He groans and tries to shoot her with his crossbow, but is stopped. No blood seen.
Anna punches Hans in the face on board a ship, sending him toppling overboard.
Olaf is impaled by an icicle but he is unharmed and it is played out in a humorous manner.
When they're children, Elsa accidentally hits Anna in the head with an ice blast, knocking her unconscious. Anna recovers, but without the memory of Elsa's ice-making power.
At a ball, Anna accidentally smacks Hans in the face.
Anna and Kristoff are chased by wolves, and attacked by a giant snowman that Elsa created. They fall off a cliff, but land in deep snow, unharmed.
Hans and his men battle the giant snowman. Two of his men make it into Elsa's castle, where they fire arrows at her, and she responds by attacking them with ice blasts. One of the men fires an arrow aimed at Elsa, but Hans redirects the shot, causing a giant ice chandelier to fall. No one is harmed.
