HasbroPlayskool Mr. Potato Head Super Spud

do you get every thing you see in the picture including the three smaller heads and parts?

Do all the potato heads have bottoms to store pieces or does just the large one store pieces?

We have potato heads from our older child that are ~10 years old. Will these parts also work with our old potatoes?

is the large potato head pieces come out, if so is it easy for 20 months old to put them back on the potato head?
