Most Pokémon in this Egg Group are commonly known as "cute" Pokémon. The members of this group tend to not be as physically large as the members of other Egg Groups, even when fully-evolved. Many Pokémon in this group appear to be mostly a head with arms and legs in terms of body shape. A rather large amount of Pokémon from this group are also Fairy-type.
It is also noteworthy that several families that belong to this Egg Group have received a pre-evolution, either in a later generation or, in the case of Togetic, at the same time. There are also several families that are predominantly female.
