Jack mentioned that she slayed a creature called the Jabberwock.

The character that was present in OUATiW was known as the Jabberwocky. However, this is most likely nitpicking on my behalf, and it was a throw-away reference that the show made in Season 2 because they most likely didn't know that they would be introducing the Jabberwocky later and they had to give Jack a reason to have Wonderland mushroom.
