There are a few in-game boosters that you can purchase to help you out of a difficult area.
Flame
Grower Booster can be used to grow any pepper on the board by three stages.
The
Collector Booster gathers peppers. Once you activate it, choose
one of the peppers and it will collect all of them.

The Hammer Booster destroys
any object or one pepper.
Create own
matches Booster – activate and then choose a pepper to create more of the same
peppers.
The Firecracker Booster can be found on Mister Claws’ levels. When activated it will scare him away for 3
turns.

Free Plus 3 Booster (+3) is the only completely free booster in
the game. Sometimes when you open the game you get the option of sending
them to your friends, and sometimes your friends send them to you. When
you open the level, it will automatically be applied when you click
accept. However, If you accept them from your messages you won’t have a
choice to use them or not because they will already be activated.
