Fire: Crumpling cellophane or wax paper gets close to the sound of a crackling fire.
Footsteps: Hold two shoes and tap the heels together, then tap the toes. Try using different kinds of shoes on different surfaces. For instance, walking in cat litter sounds like walking on gravel or snow.
Another snow sound: corn starch in a leather pouch to give a sound of snow crunching.
Horse hooves: just like you've seen in the movies, try two halves of a coconut shell.
Kiss: smooch your arm. (But honestly... why would you need a kiss in your story, kids?)
Buzzing insect: Just like we used to do to make home-made kazoos -- wrap wax paper around a comb tightly then hom with your lips just barely on the wax paper. Great buzz!
Thunder: Shake a large piece of sheet metal to simulate a thunderstorm.
Town bell: tapping large metal pot lids while holding them by the handle gives good bell sounds.
Whooshing: a thin stick swooped through the air.
Creaking: old chairs work well. Sitting on them or pushing them gives you a creak you can control.
Metal fence: a metal rake
Bird's wings flapping: a pair of gloves being waved up and down
