Out of his magic wand came flowers, ribbons and garlands of every possible colour and seemingly unending length. It came in such quick succession that everyone was left gasping. One or two young children came up to examine the thin stick wondering how it could hold so much. They were really frustrated. As if that was not magical enough he made a rabbit pop out of an empty wooden box. It went hopping around the stage. It was soon put back into the box and seconds later, he pulled out a rat, soft, white and squeaking. The little ones seemed a little frightened by this, while the others clapped and cheered loudly. This was the grand finale. The children did not want it to end. They shouted 'encore', 'once more'. But Kim gave them a bright smile and vanished from the scene.
