So... the latest updates have made almost every world have 'bonus levels' that are complete bull and unnesscarily difficult. You can't even place a few sunflowers before the first suprise attack shows up. There's also no reason to play them since all you get are pinatas, which can easily be obtained by doing literally anything else. This also ties in with Big Wave Beach, that when it was released it was heavily critized by the community because of tough zombies - and the later levels of Modern Day are almost unplayable due to early balloon zombies and all stars.
