Finding the right word

I was digging up the garden so we could plant seeds. K and Do helped for about 30 seconds, until we found a worm. After that, my job was to do all the digging, D's job was to step in the dirt and sit in the dirt and lie in the dirt and... K's job was to keep up a non-stop stream of questions--or maybe one long, continuous question: "Are you finding more worms? Did you find another worm? Are there any more worms? Where are they? Are they under the dirt? Why are they under the dirt? Do they like it under the dirt? When will they come out from under the dirt? Are you finding more worms? Did you find another worm?"
And finally--when he had apparently run out of different ways to say "Are you finding more worms?" he asked me, "Are you keepening looking for more worms?"
Yes, I "keepened" looking until the garden was all dug up, and K had a collection of about 20 worms. (We put them back in the dirt when we went inside for lunch.)
