What are all the mascots in book Speak?

There are no official mascots in the novel "Speak" by Laurie Halse Anderson. The story focuses on Melinda Sordino's personal journey of trauma and silence, and there are no animal or other symbolic representations that could be considered mascots.

However, some readers interpret the tree that Melinda starts carving as a symbol of her inner struggles and growth. While not a mascot in the traditional sense, the tree represents a crucial element in her journey and could be seen as a symbolic representation of her internal struggles.
