The reviews on Amazon are five-star with one Grandma saying:
"A lot of fun at a great price!
My 4-year old grandson and
granddaughter love the Backyardigans.
(So do I !) They play with the plushes
and make up their own adventures.
I love to see them use their imaginations.
I am always Pablo!" ~ Einar
