Bambi walks out into an open area and 3 dogs charge him, the Great Prince comes out and kicks/hits the three dogs. The dogs whimper and run away looking unharmed.
Bambi tries to act brave by walking on a porcupine's log (his property), he ends up getting stung. We don't see Bambi get stung but we hear him yell. We later see the quills in his skin (nothing graphic) and Hopper pulling them out one at a time. The whole scene has an action sequence where Bambi tries to avoid getting stung.
A deer gets stuck in a man-made trap. The deer tells Bambi to run, but Bambi sidetracks the dogs into chasing him instead. The scene is pretty long and Bambi is seen in peril a few times, some young children might get frightened during this long scene. During this scene many of the dogs get injured, although you never see the dogs get injured but you can predict what happened to them (one dog was kicked off the ledge and you can hear it wimper).
