Snakes: Go right behind them and howl. To howl, hold down X until your dog howls.
Cobra Snakes: You will find that the cobras move in circles. When you see the right chance, go next to the snake where they can't see you. Start howling when you're still next to the snake. They will move the other way, making you be behind them. This is why you should start howling before the snake moves, because howling takes a few seconds. You howl, and the snake gets knocked out.
BTW, Cobras paralyze you, making you slow down for a few seconds.
Bright Poison Snakes: Some poison snakes move in circles, or they stay still. Use the above facts to defeat these guys. You should have at least three Obaba's Antidote before defeating these snakes, but only if you aren't skilled at defeating enemies.
Bats/Vultures: You cannot defeat these animals, but to be safe from them, walk instead of running.
Brown Bears: Just sneak up behind them and howl.
Polar Bears: Sniff walk to them, and get right next to them. Then howl. You can do this while they are sleeping, or when walking.
Bulls: I do not know how to defeat bulls, sorry.
Crocodiles/ Alligators: These animals don't need to be defeated if you are at Zoomy Lake. Just swim fast or avoid them. However, in Chiro Caves, the Gator/ Croc is in shallow water. It will spin in circles, and do what I told you to do when getting cobras.
Warthogs: These little guys can be very annoying, and one killed me once. I was and still am an expert at defeating enemies. Walk to them when they are sleeping. Run away if you see them getting up. While behind them with success in not being hurt, howl at them.
Enjoy killing everything in sight!
