Lots and lots of crepe paper! Greens, browns, you can twist and plait to make hanging vines, brighter colours you could stick into a long tube shape, stuff with newspaper and tie either end to make a snake. Cover the wall in shades of green paper, attach smaller sheets of green paper (camoflaged 'lift the flap') with simple questions on ie; I roar, I have stripes. Under each one have the answer (could be pictures of lion, tiger etc.) Supply binoculars for big game spotting. Get the children to make large butterflies. I'll keep thinking!
