These Sillies are so happy to be playing with you that they light up with joy! Just give their velvet-soft, plush-covered bodies a bounce to make them flash and glow. When it's time to sit down, curl up together with the included six-page 4" x 6" Sillies storybook! Also includes non-replaceable batteries. Hand air pump with needle required (not included). Choose Lilly the Bunny, Gilly the Cat, Dilly the Monkey, or Willie the Dog.
