.. Getting into the church

Devise a tool that gets you higher while walking into the scene.

Stilts! Then you can walk high and enter the window.

Find boots ( Go look from the shed. On the shelf. ) and long sticks ( Take the scaffolding from the base of the water tower. )

Combine them to get stilts. You can now wear them (drag them on McQueen) and walk into the church through the window.
