Look about the photos and you will find on the little tree:
fish, fans, flowers, butterfly, peacocks, swans, modular boxes and triangles, fans, fortune teller units, a penquin. a parrot, and of course that shrimp!
The idea was to keep it colorful and not overfill the little tree.
Little trees like this (artificial or real) can also be decorated by special order with custom origami for other holidays.. such as Halloween, Valentines Day etc. But more often they are requested for a centerpiece for a holiday dinner or a wedding party!
