In a Cabin In a Wood
(source: there is a very similar song called "In A Cottage In A Wood" in "Sing A Song For Sixes", Girl Guides of Canada, 1975; also found in "The Kids' Campfire Book", Jane Drake and Ann Love, Kids Can Press, 1996.)
(actions in brackets)

In a cabin in a wood (trace a cabin outline with your index fingers)

A little old man by the window stood (trace a window outline)

Saw a rabbit hopping by (two fingers of one hand like rabbit ears, hopping)

Knocking at his door (knock with fist)

"Help me! Help me! Help me!" he said, (throw arms up for each "help me")

"Or the hunter will shoot me dead!" (make a finger gun, point, and shoot)

"Come little rabbit, come with me, (welcome gesture with hands)

Happy we will be." (hug yourself)

Here's a slightly different version of the song:

Little cabin in the woods (put hands together to form a teepee shape)

Little man by the window stood (put your hand to your forhead like you're shading your eyes and look around like you're searching)

Saw a rabbit hopping by (point up your index and middle finger like rabit ears, then move your hand up and down to look like hopping)

Knocking at his door (make a knocking motion)

Help Me! Help Me! Help Me! he cried (raise your hands up like you're surprised and repeat)

Or the hunter will shoot me down (make a shooting motion)

Little rabbit come inside (move you hand towards you to motion "come here")

Safely by the fire. (make the bunny ears with your left hand and use your right hand to stroke your bunny's ears)

The first time through, sing the entire song with all the hand motions. The next time through, don't sing the last line, but still do the motions. Keep dropping lines until you're acting the entire song with no words and just hand motions. Finish up by singing the entire song one more time with all the hand motions.
