To pass this level you have to save all 8 pets within it, and achieve 13,000 points. The best tactic for doing this is to play as many moves as you can on the starting section, then use the Column Blaster on the column containing the key. Remember to use Block Buster Boosters on any blocks under a pet that are causing you problems.
