Nibblers are fish that have the power to clear rows and columns of fruit. Nibblers can also clear lizards not affected by fruits being matched next to them. You can use Nibblers to cause damage to the blocks that stand in their way, but beware of Stone Blocks as those can stop Nibblers that were launched at them. Cactus blocks can stop Nibblers, too, but it will take damage from the hit.
Coral
Coral can be summoned when you collect four of the same fruit. It can clear a single row or column at a time. When Coral is hit with another Nibbler from left or right side, it’ll vertically launch to both directions. However, when you hit Coral with another Nibbler from up or down, Coral will launch in both horizontal directions.
Bitelings
You will get Bitelings when matching five or more fruit in an angle. They are a bunch of little rascals rushing in all four directions when launched.
Octo
Octo can be created by matching five fruits, and it clears three adjacent rows or columns. When Octo is hit by another Nibbler from left or right side, it will launch vertically in both directions, however when hit by another Nibbler from up or down, Octo will launch in both horizontal directions.
Bouncer
When a big fruit cascade is triggered or multiple Nibblers are launched simultaneously, Bouncer can appear. When a Bouncer attacks it will destroy all fruit, blocks and mud tiles it hits while the shockwave from the hit will cause further damage around the Bouncer. While some enemies can be easily defeated by this powerful fish, indestructible enemies and stone blocks are too tough even for the Bouncer.
You can get the Bouncer to appear more often when your game is connected to Facebook. Also, the more friends you have playing this game, the more often Bouncer will appear.
