The Sweet Kisses Ponies appeared in the My Little Pony line in Year 10. They were Sweetheart Sister ponies with sleek and slender bodies, and had lipstick lips that would appear with cold water and disappear with hot water (or a kiss from her human friend). They also had tinsel in their hair.
Unlike the other Sweetheart Sister ponies, the Sweet Kisses ponies did not wear earrings.
Each Sweet Kisses pony came with a lipstick tube with a sponge so the hot and cold water could be applied to their lips.
A common problem with these ponies is that their lipstick fades over time or no longer changes color.
