Pet Rescue Saga Level 512 Tips
You have to clear some blocks in the first and last column of the screen in order to be able to smash the wires around the two balloons there are in the two upper corners of the screen. Keep clearing the different colored blocks, from these two balloons, of the screen where possible and use the two line blasters to destroy the metal boxes. Use the two balloons when there is no other different colored blocks to clear. Use the balloon booster that it will be activated to destroy the block under the key, in order to release it and use it.
