 If you need to shuffle a list of elements, you can use the built-in function [`shuffled`](https://kotlinlang.org/api/latest/jvm/stdlib/kotlin.collections/shuffled.html).
 
-Since `Duck.values()` returns [`kotlin.Array`](https://kotlinlang.org/docs/arrays.html), by default you cannot invoke the `shuffled` function, you need to convert the result into a list:
+Since `Duck.entries()` returns [`kotlin.Array`](https://kotlinlang.org/docs/arrays.html), by default you cannot invoke the `shuffled` function, you need to convert the result into a list:
 ```kotlin
-Duck.values().shuffled() // ERROR
+Duck.entries().shuffled() // ERROR
 
-Duck.values().toList().shuffled() // OK
+Duck.entries().toList().shuffled() // OK
 ```
 
 We will not consider the detailed difference between lists and arrays in this project, you can follow to the documentation to get more details.
