Wobbly Worm was given as a Birthday Present for a three year old.
From the feedback I have received Wobbly Worm is entertaining.
Since Wobbly Worm continually moves placing the rings is harder than it looks!
Even so the child is very happy.
this was a christmas gift for my granddaughter and she loves to play it with me. very entertaining and challenging. she is 3 years old. i would recommend it for pre-school children.
