Admittedly, releasing the Chickens when mowed over is unfair. But Dolphin Riders are close to the speed of Chickens with much more health. You can't say Chickens are too fast and Dolphin Riders aren't.

And that "grace period"...you mean the period of time in PvZ1 where you'd get no zombies in a row that's lost a lawnmower? I wondered where that had gone too.
