Morphlings are a fictional creature from the Harry Potter universe, not from The Hunger Games. They are shapeshifting creatures that can change their appearance to blend in with their surroundings.
The Hunger Games features a variety of other fictional creatures and beings, including:
* The Capitol Citizens: These are the wealthy and powerful citizens of the Capitol, who are often depicted as vain and obsessed with appearances.
* The Career Tributes: These are highly trained and skilled tributes from wealthy districts who are favored to win the Games.
* The Muttations: These are genetically engineered creatures created by the Gamemakers to make the Games more dangerous.
