The adventures continue for the new generation of ponies as Pipp and Zipp take center stage! There’s no better friend than a sister...unless your sister thinks what they’re doing is waaay more important than what you’re doing! Pipp has been super stressed because the new, edgy musician Carotang has been totally stealing her limelight. But Zipp has been too busy helping Queen Haven prepare for the Royal Dinner at the castle to even notice Pipp’s distress. After a huge fight, they both make a wish…but wishes don’t come true…right? Volume 4 collects issues #16–20 of the ongoing comic series.
