Dan and Kate have moved into a new house that has substantially more acreage on it than they did previously. They have been clearing out undergrowth and working on getting it ready to have a garden on it.
Of course, it's a big job, and who better to employ than Margaret and Ellie? They're cheap, they're reliable (at least if you pick them up), and they certainly aren't afraid of getting their hands dirty.
They didn't make much progress, but I think with a good, solid effort, they could have the garden ready by Spring 2020.
Ellie just needs to get a little taller so that she can hold the shovel properly. Then it'll all go much faster.
