Sounds like with a recent update - either: (a) each additional piece requires more cleans (ie. more friends); (b) the cleanings needed to get any piece increase as you increase levels; or (c) it could depend on which stage you're up to, so it could increase every third piece?

Zploughs comment would also imply that new players can now start collecting pieces and building the foundation as soon as their quest starts on Level 5, rather than needing to wait until at least Level 7.
