I bought this along with the other two (Wheels on the bus and Pat-a-cake).
This is my favourite; the songs are fun and well presented. There are also 'jokes' and rhymes and speaking in between the songs linking the songs together in a zoo theme (not sure that comes across from the title). A few songs I hadn't heard, but mainly traditional songs I recognise from my childhood.
I play it with my son who is 8 months old and sing along, bounce around and do the actions etc and he really enjoys it. Good for days when you need a bit of extra inspiration. Obviously when he is older I could play it all the way through in the car, but at the moment I just flick between songs and miss out the speaking.
I think this is well priced and all in all a good buy. Would recommend from about 6 months, but think it's probably more suitable for older babies/ toddlers/ young children.
