There's a party going on! The grandparents have come over, there's a cake in the oven, streamers are hanging from the ceiling, and the camera is ready to make memories! Today is the day Luly turns 5, and the whole family is excited to celebrate. Well... almost the whole family, for Lulu, the star of the day, is suddenly overcome by a huuuge fear: she doesn't want to keep growing up! Because growing up means leaving the cozy cocoon of childhood behind, and seeing her world change. But Mom is determined not to let her daughter ruin her party, and to stop her, she's ready for some literal acrobatics!
