Pop-up Toddlerobics

This selection of well-known action rhymes - Row your Boat, Peter hammers, I'm a little Teapot, etc - is illustrated with the help of moving parts, operated by levers and wheels. The effects are sometimes fun, occasionally bizarre, and probably won't last very long in the hands of little ones. My copy lost the action of one page almost instantly and a warning on the back advises that the book is in fact 'not suitable for children under 36 months'. I can't think who else it's intended for, so prepare for some short-lived fun.
