Anyway, this is how we did ours, and how they turned out.
Step 1: What We Used
To decide what we wanted to use for our bentos we basically went to the grocery store and just grabbed anything and everything that was colorful, inspired us, or had promise.
Some of the needs:
-Rice (more detail on this in step 3)
-bag of sliced mixed veggies
-whatever your heart desires
Step 2: How to Make Your Sticky Rice
* 1 cup medium grain rice
* 1 cup water
* 1 tablespoon water
1.Wash rice several times (until the water is clear).
2.Let soak for a few minutes in colander.
3.Put rice in pan with tight fitting lid and add the water.
4.Cover and bring to a boil.
5.Simmer over low heat for 15 minutes.
6.Remove pan from heat and quickly stretch clean tea towel over the pot, cover with lid.
7.Let sit off heat for another 15 minutes.

Or, you could just go to a local Chinese or Japanese food restaurant and just order a box of plain white rice. Around where I live it's only $1 for a small, but they may look at you like you're insane.
Step 3: Play With Your Food!
Here's the fun part!
Get yourself a nice handful of rice and start molding it (just like you would clay) into an awesome animal or whatever you want.
**To keep the rice from sticking to your hands, keep a bowl of water handy to keep your hands moist**
Unfortunately I don't have any photos of this step, but that's alright because this is the part where you use your own imagination anyway :)
Once you get the shape of your buddy down, you can start adding the details with the other food.
The way I did it with walrus is that I formed him in my plate, and once he was how I wanted him I filled around him with the split peas.
His eyes are cut out circles of seaweed
His cheeks are the ends of strawberries
The spots on his nose are the little "tree leaves" of broccoli
His tusks are walnuts
The pink fish are molded rice colored with food coloring
Step 4: Eat Em' Up!
....actually we ended up not eating ours because we didn't want to part with them.
I've specified on some of the pictures what we ended up using for different parts of the bentos.
Hope you all have as much fun making them as we did!
