So I was in the kitchen the other day, Very Busy, and V was babysitting The Bhablet. I stuck my head out of the doorway and saw V sneaking away those bricks, as usual.
I heard some funny noises... If I were to investigate all the funny noises in this house during their waking hours I'd be even busier than I usually am, which is definitely not welcome, so... I ignored them. (It sank in after a while that someone was humming the theme of Johnny Sokko and His Flying Robot.)
Work took me to the room a little later. V held up something he called a robot (with a wheel for a nose) and told me with a hilarious mixture of defiance and sheepishness that he'd made it. I made polite sounds and ran back to my cooking.
Some more funny noises, louder this time.
Went back to find the bricks all over the floor and a triumphant Bhablet. V, this time combining fatherly pride with annoyance explained that Bhabzilla had destroyed the robot.
