Missing fields on Account objects in Developer edition

I am trying the Trailhead challange for Formula fields at

and the challenge is to add a formula field on the Case object referencing the Last Activity Date of the Account object.

But the Account object doesn't have a Last Activity Date (and neither does the Case object) - so how can I complete that challenge?

Hi Philip,
There is a field Last Activity In Account. When creating the formula, click on insert field -> Case -> Account -> Last Activity.

The final formula will look something like this:
Today()- Account.LastActivityDate

Thanks for your help guys, it turned out I was logged into my employers sandbox, rather than the developer edition!
