Wibbly Pig Likes Bananas, by Mick Inkpen

Wibbly Pig (depicted on the cover with a banana skin on his head, much to DDs mirth) chooses his favourite from a variety of items (such as hats or places to sit), and the reader is encouraged to choose too, right until the very last page on which Wibbly Pig cannot decide which teddy he likes best and the reader is enticed to choose alone.
With it's colourful pictures and possibilities for discussion now DD is getting older ("why do you like that hat?" "Because it is pointy and i can poke people with it!", it would make a long lasting addition to a young toddlers collection.
