In Chapter One, an the first screen where you have control, take the windsock from the center-right area. Do not tie up the end with string to make a net just yet. Take the Nodtarine bottle from the left side and the crutch from the right side. Use the bottle to open it, then use the open bottle on the worm to get the worm drunk. Take the drunk worm and combine it with the crutch to create a slingshot. Combine that with the cork to make a loaded slingshot. Use the loaded slingshot on the fish to force the pigeon to descend from the windowsill. Use the open windsock on the pigeon.
