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.

Elmo jack in the box
My 2 year old grandson loves this and plays with it all the time! Each time he still acts surprised when Elmo pops up :)

Love the idea, mine was defective.
Absolutely loved this item and the idea of it, but mine was defective when it came in. Elmo would not fully pop out when it was supposed to and had to be pryed out. Tried multiple times before deciding to return. A family member ordered one as well and theirs was perfect!
