A few (less than a dollar from LEGO buy it by the brick) blocks make a cute little penguin. If you swap out the "tooth" part that makes a wing with a holder piece, you can put all kinds of stuff in it.
Here's a set of twenty. Some with oars, some with weapons, and my favourite, engineer penguins with shovel, pickaxe, spanner, and hatchet.
