Rob remembers that he had to change the lightbulb in the dining room.
But rather than waste time getting the ladder from the garage, he decided to use his belly button to get bigger and change the lightbulb.
So he first fetched the new lightbulb he bought yesterday, and then he took off his slacks, keeping on his boxers and socks.
Then, he pressed his belly button and started growing.
Once he was tall enough to reach the lampshade in the dining room, he pressed his belly button again, and he stopped growing.
He was able to change the light bulb easily.
Satisfied, he set his belly button to 'shrink', and one press of his button shrunk him right down to normal size.
Rob liked his new belly button.
