Tara Lipinski's dog Dublin joins the four remaining teams to introduce a precocious pet topper challenge. Then Johnny Weir and Tara introduce an engaged couple, who ask the bakers to combine their love of nature with their love of the city. They both like cookies more than cake, so the bakers must find common ground. Judges Kimberly Bailey, Maneet Chauhan and David Tutera will send three teams to the finale.
