The Herbicide Squirter was used to tap multiple Bob Clones at once. It was similar to the Bunny Stunner during the Easter 2014 Event, the Weapon during the Treehouse of Horror XXV Event and the Elf Bottler during the Christmas 2014 Event.
The Herbicide Squirter was upgradable with Corn and DNA. Each upgrade increased the blast radius of the herbicide and some of them also increased the reward (Fertilizer, Corn or DNA) for squishing Bob Clones. A complete list of all upgrades, their cost and reward is presented below.
- When the player reached the Upgrade Level 8, a 3-Day DNA Sale was unlocked in the Store. For 25 Donuts one could purchase 700 DNA.
