I have just come across this Japanese page of fun printable toys. You will have to guess at the instructions (unless you can read Japanese!) but there are illustrations which show you how to put the toys together. Click on the links to find the printables themselves - bearing in mind that sometimes you will be taken to the printables, and sometimes to a commercial site selling craft supplies! I particularly liked the pop up racoon and cut puppets and the skittles.
