Isabelle appears as an Assist Trophy. Her abilities are giving Food to the one who summoned her.
Isabelle is the mayor's highly capable secretary. She can be forgetful sometimes, but you can always count on her for imformation about the town. She wears her hair up in a bun that makes her look like a shih tzu. Mostly because she is one! She also has a twin brother named Digby.
When Isabelle throws food at the person who summoned her, they will automatically pick it up even if the player didn't press A.
Though opponents do have to press A in order to eat the food.
