No matter what world (and therefore what time period) you delve into in Plants vs. Zombies 2, there are always the same three zombie types that occur in slight variations in each of them - the Regular, Conehead, and Buckethead zombies. These are usually very straightforward to defeat. The other zombies in every world are unique to each time period. Some of these require more thought-out tactics to make sure that they don’t get on your nerves. Take the Dodo Rider Zombies in the Frostbite Caves as an example.
These little buggers can get really irritating if you don’t get rid of them in an easy manner. This zombie type can flap and jump over barricades. Your Wall-Nuts will not prevent them from approaching. Jumping over an obstacle requires them to pathetically fly for a few seconds. Use that moment to simply wipe them from the battlefield! How? By always equipping yourself with the Blover. As you might remember, this plant blows away all zombies in the air, including the Dodo Riders. This will allow you to get rid of them before they have a chance to destroy your plants.
