You go to fireclan, and go to the sandy beach area. Then go to the right, and click on the cave. Click the left hollow inside the cave and youll see a purple and blueish she-cat. If u need poppy seeds for the deputy, click on the leaf and go to the deputy. If you want to be a medicine cat, click the purple and bluish she-cat and type "yes" when she asks you to be her apprentice. Then, like lunarclaw says, go to breezestar and type "2" if it says ask to be medicine cat. Theyre ya go!
