To unlock these three achievements, you only need to get 16 total Wipeouts out of the possible 25. To get a Wipeout, you basically need to have a ton of bombs explode within a second or two and all the gerbils fall below the line. It is easiest just to spam bombs fast and sit back and watch the results and adjust on your next attempt as necessary. You can also earn a Wipeout by using only a single bomb (I think maybe two).
