The World's Number One Witch lives in the northeast corner of Chestnut Town. She has a large ego, which conflicts with her neighbor, Gareth. Tabitha will give you hints as to the gift preferences of the villagers. She also will give you tomorrow's weather report. Sometimes you have to talk to her a lot to get her to tell you the weather report.
Some of the suggestions that Tabitha makes are not always possible. For example, she states that Emily likes Flour, yet Flour isn't an item you can gift to anyone (i.e., you can't hold it in your hands to give).
