You start at the outside of Elephant Restaurant (Wild Things.)
Also known as Poison Alley, this challenge will keep you on your toes. Lots of powerful weaponry, including the coveted Grenade Launcher with fire rounds. Yes, fire rounds!
But there are also tons of enemies that are able to poison, and some others that can instakill. Bees, scissortails, bites and web spinners are around every corner.
There's a particularly nasty seed with tons of weaponry but extremely few healing items. There's also another seed which hides a very valuable secret outside the hospital...
As you can guess, Cindy is very useful with her herbs, as is George with his pills.
