By the way, I recommend NOT doing it during the hot Aussie summer like I did ;)
Step 1: What You Need
• 2 beach balls (somewhere between 40-70cm diameter, depending on head size)
• Glad wrap (cling wrap, saran wrap, whatever you call it in your country)
• PVA glue
• Green paint, white paint and red paint or red tape
• Black permanent marker
• Strong tape
• Clothes pegs/clamps
• Masking tape
• More paint
• Glad wrap
• Green shirt (preferably long sleeved)
• Green gloves
• Long green pants
• White material/shirts
• Large brown shoes, I used a pair of ugg boots
• Backpack and a brown covering for the shell
Step 2: Plan
Take some photos of yourself, draw some pictures, figure out the scale of everything.
I mostly worked off a Hungry Jacks Yoshi figurine which was approximately 20 times smaller than real life. This will help you determine the size of the beach balls.
Step 3: Paper Mache Mini-instructable
1. Half-fill a plastic chinese take-away container with warm water.
2. Pour in some PVA glue (the more the better, I only used a small amount).
3. Here I added some plaster of paris. After a while I realised that the plaster does more harm than good. Don't use too much.
4. Flour. Lots of flour. Not too much, but enough to get a fairly thick mixture.
5. Dip a strip of newspaper in the mixture (I found that newspaper tends to rip one way much neater than the other)
6. Use two fingers to squeeze off excess mixture back into the container
7. Apply the strip
Step 4: Paper Mache the Beach Balls
Cover the ball with a layer of glad wrap in case the paper maché sticks to the ball. Apply the strips to the ball, do as many layers as you need to until it is fairly hard. I think I had ~6 layers on each ball.
Once dry, cut around the circumference if it is for the nose. (If you are only using one ball, the first should be the nose) You will probably cut the ball. Having the two eggshell halves makes the inside dry better and will make later steps easier.
For the second ball, it is important to know that the head is more elongated than the nose. If you are reusing the first ball, it will probably deflate as you cover it. When you cut the head, just cut a hole in the bottom (where your head will eventually go). If you had reused the ball, it will probably have sunk on the point it was standing anyway. Mine did, so rather than cutting a hole, I just never made that section.
Step 5: Paper Mache the Eyes
Step 6: Make the Spines
Step 7: Attach the Nose and Head
Step 8: Attach the Eyes, Spines and the Rest of the Nose
Line up the front half of the nose with the back half and tape them together.
Tape the spines on.
Add another layer or two of paper maché over the whole thing.
Step 9: Paint!
Paint the nose and half of the eyes and head green. Paint the rest white and paint the spines red, or wrap them in red electrical tape (I did).
Be careful what paint you choose. My newspaper was still readable after 3 layers of the first green paint, so I had to get a different one. It may be a good idea to do a white base layer.
Also, try adding some PVA glue to the paint to give it some extra shine.
I went around each of the edges with permanent marker once it was all dry.
Step 10: The Body
For the white part of the pants I used a white bag, but I probably put too much stuffing in there.
Step 11: Tail + Backpack
In the morning I stapled loops of elastic around where the legs and waist would go. The waist one kept snapping so I eventually just tied knots.
For the saddle I just covered my backpack with the orange cover of one of the cushions I borrowed and held it with staples and safety pins.
