Saszi is Bookworm's little sister, a hyper-active and fun spirited young cat. She takes her doll, Miss Pawsy, with her almost everywhere she goes. Saszi looks at life as one big party—in which it is always her birthday, complete with singing and dancing. She loves playing dress up and making something or someone prettier than one should be. She loves her friends and has a loving, but sometimes irritating bond with her sister. She also mistakenly bop others with her doll.
