Model Yak

[karion]

Could anybody help me with a project i have. I play in a role play game and i need to make a yak/cow animal to pull a pallaquin or cart. I have the head OK but how would i make the body? the animal would have to be about 2 foot wide and about 5 foot long. The idea would be to make it so it is easily transportable and in pieces like a wooden frame that can be covered. Space for transporting the said animal is only moderate. Does anyone know where i could boy a blow up one or has anybody got ideas or plans how to make it.
Thanks

You could try papier mache - lightweight and can be built in sections to be fitted together.
