Riley Red Velvet,the oldest daughter of Pinkie and Cheese Sandwich.Headstrong and free spirited girl.She is usually easy going and friendly with everyone,but you better not waste her time,get straight to the point and move on,dude.She knows her way around ponies and can easily read them,that is why she is a huge flirter,she can make the most collected one into a blushing and stuttering mess.

Benjamin ''Banana'' Split.He is quiet and timid,but likes to make people smile:he wants to become a comedian and make ponies laugh just like his parents,but his insecurities seem to take over everytime he is on stage or on front of a crowd.
He is also and excellent cook.

Finally introducing Pinkie's kids!Yay!
The reason why they aren't hearth ponies is because in both Cheese and Pinkie's family there were a lot of pegasi and unicorns,so their kids inherited those traits.
