Well they are ponies and they are younger than their princess so she calls them her little ponies. And the friendship is magic is from episode 1 and 2: the elements of Harmony parts one and two. The elements are magic obtained by twilight sparkle and laughter (pinkie pie), honesty (apple jack), generosity (rarity), loyalty (rainbow dash), and kindness (flutter shy). Which make up the meaning of friendship. :) happy to help
