During a scene where three of the protagonists realize how deadly the wild is, we see a bird eaten by a carnivorous flower (the flower comically burps out it's feathers afterwards), a mouse is dragged offscreen by a snake, escapes only for a eagle to grab him and swoop off, and a duckling is swallowed by a crocodile.
A human skeleton attached to a parachute hangs from a tree; a decrepit plane is nearby.
Julian uses a human skeleton hand to point and make gestures.
Many animal control officers, with their guns drawn and looking scared, surround several animals, and shoot a Alex in the buttock with a tranquilizer dart (Alex is shot on two different occasions).
An old lady beats up Alex by hitting him on the head with her purse repeatedly, and also kicks him in the crotch.
Gloria hits Alex with a large stick and keeps hitting him (she is trying to save Alex from a spider on Alex's back).
A penguin knocks a man out with a strike to the neck, and a penguin hits a man in the face (the man is tied up and his mouth is taped).
Alex is hit in the face with a tree branch, he steps on a thorn, a tree falls on him, and he's caught in a large spider web. He is also hit by a coconut and falls down a waterfall.
Hungry Alex jumps and bites a zebra's backside (they're friends, but the lion is starving and hallucinating about steaks); we see the zebra later with a large Band-Aid on its backside.
A penguin says that he and his fellow penguins killed some humans and "had eaten their livers" (he's kidding).
