Early, Perry is seen traveling two doors down from the Flynn-Fletcherhouse to Doofenshmirtz's house. Therefore, Phil must live on the same street as Candace, Phineas, and Ferb--Maple Drive--and live three doors down. This would also put him across the street from the Garcia-Shapiro house. How they see him is unknown, but when Heinz Doofenshmirtz buys a house on Maple Drive, he has little tolerance for Phil, complaining about his trash, his dog, his apple tree, and above all, his leaf blower, which propels all of Phil's leaves onto Doofenshmirtz's lawn. Bent on revenge, Doofenshmirtz invents an "Atomic Leaf Blower-Inator" to blow all of the leaves and more back into Phil's yard, but it backfired and his invention blows the leaves in the opposite direction.
