imaginary grandchildren

We were in the car, on our way home, when Dennis asked "did you know I have 6 boys and 3 girls?". I asked if they were his team or his class (was he a coach or teacher?), and he said no, they were his kids and he was their daddy. And then he told me their names. The boys are "Atcha, Black, Blue, Lacka, Figaro, and Goldfish" and the girls are "Bleeka, Leeka, and Karate". And my spellcheck has just had a field day! Apparently, the girls "live at Gran's house, thank goodness, and we need to drop them off there". And the boys, well "they live at our house, all in different rooms, and my boys can get pretty loud!". Dennis must be planning fruitfulness in his future!
