How do you beat Invasion of the Patty Snatchers

To amend my previous reply (below) I've discovered that each level can be beaten with just Pickle Flickers - no upgrades necessary! Just add as many flickers as you can as soon as you can, positioned so they can flick when the bots pass in front and again when they pass behind! Easy!
