Dot To Dot

From dot number one I draw a line To dot number two with a pencil fine, Then on to three, off to the right Back to dot four, a curious sight, Number five points me in a sharp angle Then up to number six without a tangle, Dot number seven turns to the left I am drawn to eight by fingers deft, Number nine was not off too far From number ten to create a star! I sharpen my pencil before I delve Into number eleven to number twelve, With a zig and a zag to thirteen, fourteen Black dots form a shape yet to be seen, A puzzling mystery with fun begot On to fifteen, sixteen, I'll give it a shot, Just what would emerge as I drew Seventeen, eighteen, I wish I knew, Dot number nineteen connected without fail To twenty, to give my star it's shining tail!
