Classic Toy That Never Gets Old!
My 8-month-old is absolutely captivated by this Elmo jack-in-the-box! She giggles with anticipation as the "Waltzing Matilda" tune plays, and erupts in laughter when the soft Elmo plush pops out. The sturdy metal box with vibrant Sesame Street designs has held up perfectly through daily play. At 5.25 x 5.25 x 5.5 inches, it's the perfect size for little hands. This timeless toy brings endless joy and smiles—highly recommend for any Elmo-loving baby or toddler!

Elmo -in-a- Box !
Purchased as a gift for my grand daughter who happens to love Elmo. Cute toy with a little red Elmo who pops up and makes you jump if you’re not expecting it. It’s still working since December so that’s a good sign !

Cute but could be sturdier
For the price I wish it was a little better constructed. Elmo’s arm gets caught every time it shuts which makes it difficult for a toddler to do it alone. The lid is thin and can be bent easily. The music is very soft. The colors and presentation are very fun but it’s a little difficult for an 18 month old to play with on her own.
