The yellow origami paper I have is such a cheery color, it always manages to brighten my day. Know what else brightens  my day? Rubber duckies. And this one can even float in your bath! (though it might get kinda soggy)




This model is by Jeremy Schafer which I found on the Ultimate Origami Resource site under misc. It is rated three stars out of five and is definitely would be achievable for a low intermediate folder. There's not any sinking, just lots of petal folds.
