Guide

Walk over to the pig food and walk over it in order to grab it. Once you have it, walk to the two X marks and place the food in trays for the pigs using the place() function.

player.place(food)

After placing the food, walk to the lighter X mark and call the piglets by putting their names in a list and using a for loop containing the speak() function to call them out. The names of the piglets: "Peggle", "Peter", "Piper", "Pedro" .

To complete the level, set up the for loop and add the call message "Come here %s" inside it. By adding the x value, the for loop runs through each entry in the list until it reads out all the names.

names = ["Peggle", "Peter", "Piper", "Pedro"]

for x in names:
    player.speak("Come here %s" % x)
