please help :\

Challenge Task 1 of 2

In the editor, I've provided a simple protocol to represent an animal.

For the first task, create a protocol named PetType. PetType should inherit from AnimalType and require an additional gettable stored property, cuddlyName, of type String.

protocols.swift 
protocol AnimalType {
  var numberOfLegs: Int { get }
}
protocol PetType = AnimalType {
var cuddlyName: String { get }
}

You've nearly got it! You need to use a colon instead of an assignment operator between PetType and AnimalType:

protocol PetType : AnimalType {
var cuddlyName: String { get }
}

I hope this helps!
