 You will have `Animal` which will an object and will have the following properties:
 - `canEat`, `canBreath`, `isAlive`: All booleans, set to true.
+- `name`: set to `"Anonymous"`.
 - `WhoAmI`: Function that returns a string, here it will be `"I'm an animal"`.
+- `NameToUppercase`: Function that returns `name` to uppercase.
 
 The following objects will inherit from `Animal` and add/override fields as follow:
 - `Dog`: adds property `canRun` set to `true`.
 - `Bird`: adds properties `canFly` and `makesEggs` set to `true`.
-- `Dodo`: overrides `canFly` and `isAlive` to `false`.
+- `Dodo`: inherits from `Bird` and overrides `canFly` and `isAlive` to `false`.
 
-All of them will override `WhoAmI`, returning `"I'm a [animal name]"`.
+- All of them will override `WhoAmI`, returning `"I'm a [animal name]"`.
+- All can accept a specific `name` as argument when created or use the default in `Animal` if no argument is provided.
 
 > There are many different ways to work on prototypes, we suggest to use `Object.assign` and similar functions, but feel free to experiment other ways to understand the differences.
