When Dorothy meets Scarecrow her pigtails are short (just a few inches below her shoulders) then her hair length changes and it's much longer down to the middle of her chest. It goes back and forth from long to short in this whole scene.

When Dorothy and Scarecrow come across Tin man he has his axe in his hand. He then begins to sing his song "If I only had a Heart." While he walks out to the yellow brick road singing and dancing you'll see that he, Dorothy and Scarecrow are not holding the axe. Dorothy is only holding her basket and his oil can. Then it goes to the scene of when the Witch appears and he doesn't have it during that whole scene of their discussion with her. After that the three of them walk off singing "We're off to see the Wizard." You do not see him holding it then either. It just suddenly appears as they are walking into the forest and they begin to sing "Lions and Tigers and Bears."
