June is happy to get a new neighbor, Mae, and soon the two of them are best friends and having adventures determined by the Wonder Wheel that they spin each morning.

Eight-year-old Grace is excited to learn that her best friend, Mimi, is going to become an older sister, but when both try to be "mother's helpers" for a family renting a house on their street, little Lily likes Grace best, causing Mimi to doubt herself and Grace to form a plan to fix things.

Best friends Randolph, a beaver, and Ivy, a goose, do everything together until Ivy is invited to a girls-only birthday sleepover party and Randolph, full of bad feelings, tries to spoil her fun.
