This is a bit naff doesnt roll very far and doesnt go anywhere on carpet 7 month old daughter seems frightened of it and cries every time she sees it it doesnt roll around on the carpeted area very well and makes alot of noise on the wooden floor however thats a small price to pay for the level of enjoyment he gets out of it however it hasnt encouraged him to crawl he will just wait for it to roll back towards him lol like the the colours and all the sounds but the turtle on top that spins my 10 months old could take that turtle off and underneath is a metal spike very sweet and not to annoying
