Summer is the only daughter, second eldest of the Hugglemonster family, and Henry's older sister. She sings and dance almost everywhere she goes. She often gets upset and over-acts when things are hopeless. She also hates disappointing her fans.
Summer wears red shoes throughout the entire series as well as a yellow bow, although she takes off the shoes where she's swimming. She often wears an aqua tutu for ballet, sometimes with a silver tiara.
