Astuto is shown to be a cautious, good hearted fox. She is also very caring for her cubs.
Beshte unknowingly tramples Astuto's den, destroying it. She is disappointed and worried. Later, when Beshte attempts to apologize, Astuto runs away in fear. She, along with all the other animals affected by Beshte's destructive mishaps, are summoned to the Tree of Life, where she learns of Beshte's true nature and forgives him after Pinguino explains.
