Pet Rescue Level 339 Tips
With the line blasters destroy the metal boxes under the pets, bringing them in the same line. Keep at least one or two line blasters to destroy the wooden cages. Use the paint brush boosters in the last phase of the level to clear the blocks under the pets and rescue them. If any pet is caught in a cage, destroy it with the rocket booster (that it will be activated till then). I am afraid that if two or three pets are caught in cages you’ll not be able to pass the level.
