Donuts and marshmellows - where did they come from ?

Marshmellows are from the base game. You use them at the pit fire.

Rainbow cookies I believe come with Generations, where if you'd ask the imaginary friend to get you a snack he/she could fetch you a rainbow cookie.

That's right, it does come from Generations. So does the donut. Rainbow cookies, spaceship cookies, and donuts are some of the things that the imaginary friend will snack on. I had forgotten that until you mentioned it. :-)
