Alien Mutations
Understand the puzzle
The exact puzzle
An alien has four parts: Head, Body, Arms, and Legs. Each part starts as a Square. Commands set a part's shape, and a later command about the same part replaces the earlier one. Run these in order: Head = Triangle; Legs = Circle; Body = Triangle; Head = Circle; Arms = Triangle; Body = Circle. After all commands, what shapes are the Head and the Body?
