This Peophin and Gelert are the older siblings of Kiki. While they were busy getting ready for winter, they told Kiki to play outside. They woke up the next morning to find that Kiki and her friends had done all the decorating for them, allowing them to enjoy the rest of the season.
Whilst it is confirmed they are a Peophin and Gelert, it is unknown which is which. They appeared in issue #25.
