The Jettisons is an achievement in Plants vs. Zombies 2. It requires the player to clear out or blow away 30 or more flying zombies in one level using Blovers. It is worth 10 points on Game Center for iOS Devices and 500 XP on Android devices.
Its name is a portmanteau of the cartoon The Jetsons and "jettison," which means to discard from an aircraft, which references getting rid of flying zombies.
If you do not plan on playing Terror from Tomorrow too much, remember that this achievement works on any other zombie.
Dead Man's Booty is also an alternative to earn this achievement. It must be done on a four-flag level. On that level also, either Swashbuckler Zombies, Seagull Zombies, Imp Cannons, or Pirate Captain Zombies must be present so it can be completed easily.
This achievement, like many others, can be completed on a Piñata Party, although the chance that at least 30 flying zombies will appear on one is small.
Keep in mind that you do not need to clear out 30 zombies at once, it just needs to be 30 in total in a single level.
- Despite saying that Jetpack Zombies have to be blown away, any other zombies in mid-air also count.
