Chain Reaction

Chain Reaction is the fourth Vasebreaker level. It involves the use of the Jack-in-the-Box Zombie to open lots of vases.

Contents
There are 25 vases (23 mystery vases and two plant vases).

Plants

 * Four Left-Facing Repeaters
 * Eleven Puff-shrooms
 * Four Hypno-shrooms

Zombies

 * Seven Zombies
 * One Football Zombie
 * Eight Jack-in-the-Box Zombies

Strategy
Break the vases to reveal Jack-in-the-Box Zombies as they destroy all the vases around them. Place Puff-shrooms at where the Zombies may end up and when possible, plant Hypno-shrooms next to a Football Zombie not meeting any resistance. Be careful, however, as the wrong vase may result in a problematic chain reaction of multiple tougher zombies attacking at once. Make sure to be prepared for the event, as it may be the main reason you fail frequently.

Trivia

 * There is a sequel of this level called Another Chain Reaction, which is harder.
 * This level focuses on the Jack-in-the-Box Zombies breaking all the vases as they immediately explode when they are revealed. This is also why it is called Chain Reaction.
