Monster shows up in the results versus Zombie


var myTown = Town()
myTown.changePopulation( by: 500)
let fredTheZombie = Zombie() = myTown
fredTheZombie.terrorizeTown() printDescription()

When I run the program it shows “Monster is terrorizing the Town”. How can I show that “fredTheZombie” is terrorizing the
the town. The only way I can do that is by changing the default value in the Monster Class.
