These wooden toys by Karl Zahn are so beautiful and imaginative.  They include a set of 5 stacking crocodiles and a range of animals that come in pieces for you to build.  You can also interchange the animal parts to create new creatures.  But these toys aren’t just for play; they’d look equally great displayed in a nursery or even on an adult bookshelf.  My favourite is that little elephant although the stacking crocodiles are pretty cool too.
