Pet Rescue Saga Level 514
Target: Save 4 pets
The Pet carriers, and blocks under them, are the only ones of their colour in this level.
To open them you will need to get a locked block (or two) positioned above the middle of the pets, then clear any blocks from between the two carriers.
You can use matches, or the hammer booster built up within the level, to do this.
Once there are no blocks between them, and none are able to fall from above, the pets will slide together and be able to be opened.
Do the same with both sides, or if you’re feeling adventurous, try to get all four together before you free them!
