This build is OUTDATED. This means you will have to improvise to make it work. Builds are outdated when Power Pills (or Free Pills) are included in the strategy. Free Pills have been removed from the game because players stacked the pills with Power Pills Turbo.
Acid Spit: Tentacle Soup/Overcharged Metabolism/Split Spit
Grow Weedling: Overgrowth/Flex neck/Bag of Seeds
Bite: Rotten Teeth/Filed Teeth/Dental Bracers
Misc: Piggy Bank/Power Pills(Free)/Your choice
As soon as you land you want to get your Piggy bank and Power Pills then buy Grow Weedlings then Overgrowth. Take out some critters to give you 1 Weedling and place that down in a hidden area. Keep on biting Heores and bots/creeps to keep on replenishing damaged weedlings. As soon as you can get Acid Spit and use that to scare of Heroes from your Weedlings. The next thing to do is buy Bag of Seeds then Overcharged Metabolism. Afterwards get Tentacle Soup then Split Spit. When buying the Bite upgrades do so in what ever order pleases you.
Play Style and Tips
Your job is to scare off Heroes and place masses of Weedlings in small spaces. Use your Acid Spit to lay traps for bots and escaping Heroes. When 2+ bots attack a turret place down all available weedlings to help them out. By the time your weedlings are dead you could have bitten enough times to have a full stock again. Make sure you are never caught without a Weedling otherwise your in trouble. Use this build for supporting allied bots and heroes and keeping enemy heroes at bay.
