Dan saw his sister wave her wand, and then he saw that he was now outside. His feet dug into the ground, and spread this way and that. His hands faced the sky, and bark grew all over them. His head turned into more branches, and his branches grew leaves. He stood there, nothing but a tree.
"Don't you love it!" Kat said, coming out on the lawn. "Here, have soem water." She poured some water into the ground, and Dan felt his roots sucking up the water. He felt his leaves soaking up the sun. He was just another tree in the ground.
