Press W to Suffocate Animals and drag them like Croc, by doing this you'll cause them some damage. Although this ability also works on predators, it's interrupted when they hurt you. Ocean animals can be a target due to their constant need of water.
The Boa Constrictor appears as a light-brownish coiled-up snake ready to attack. It has a forked tongue sticking out of its mouth, has small nostrils, and has a threatening, yet derpy glare due to ovals by its eyes. It also has a straight line going above and between its eyes. It's tail is extra long, so beware of biters. A small easter-egg shows that the details on the constrictor's body are actually River Currents.
Its graphics change when constricting. It will spring forward and "coil" itself around the victim.
A great way to level up as Boa Constrictor is to stay by the Seashore, wait for an Orca to come, then snatch it onto Land and suffocate it! Sounds harsh, but it's good to know. If you are using this strategy, please note that the Boa Constrictor is extremely slow at swimming, and some Orcas may know what you're doing.
You can also hunt for Crocs, Rhinos, and Cobras, but Bears are your easiest target as you can climb Rocks and Hills. Cobras are easy too, but Rhino and Croc can be challenging to eat. Once again, chase your prey until you get close enough, then bite into it and suffocate your prey. This should kill it slowly, but sometimes your prey may live, but very weak. You should be able to kill it in one bite after. If you see a Hippo or Orca with low health, you can also kill them with your ability.
Watch out for Giant Spiders, as they can easily trap you in their web, and quickly eat you. Be on the lookout for webs, as it is a sign that a Giant Spider is near you. Do not attempt to tail bite it, as it can shoot a spider web at you, or quickly turn around and Poison you, and you'll most likely die of poison.
You can kill predators with your ability but the ability deactivates if you are damaged so only attempt if predators have EXTREMELY low health.
