My favorite is a little stuffed rocking horse with buttons as it's rocker. (I know, it doesn't quite make sense) My mother hand made our ornaments when we were small so the tree would be 'child' friendly and still only decorates with the hand made ornaments....so it's now 'pet & grandchild' friendly.

As a kid I loved a tree ornament which my parents brought back from their visit to China. It was a koi, and it had blue/lightgreen stripes (stripes were metal layers over eachother.. hard to explain).

What I also loved were fancy balls, but uh... well, let´s say I don´t blame my parents or my fiance for not letting me hold anything fragile.
But I still love em.
