Once upon a time, there were three billy goats. They were brothers, one was small, one was middle-sized and one was huge, and they lived in a valley, eating the grass of the meadows.
Every day, they looked across the valley at the lush green grass on the other side, but they couldn’t get over to eat it, because the only bridge over the rushing river was guarded by a terrible troll who ate all passing creatures.
The goats thought how they might defeat the troll to cross the bridge.
One afternoon, the smallest goat approached the bridge. His little hooves went “tip, tap, tip, tap” on the bridge, and out came the troll, shouting “WHO’S THAT TIP TAPPING OVER MY BRIDGE? I’M A BIG SCARY TROLL AND I’LL EAT YOU FOR LUNCH!!!”
“Err, I’m only a tiny billy goat, mostly skin and bones, don’t eat me mr troll sir” trembled the little goat “my brother is coming along, he’s much bigger and fatter than me, you should eat him instead”
“VERY WELL THEN” bellowed the troll “OFF YOU GO, BUT WHEN YOU ARE BIG I’LL GOBBLE YOU TOO”
The little goat tip-tapped across the bridge and away, and the troll sat drooling under the bridge, anticipating his lovely goaty dinner.
Later that day, along came the middle goat, Trip Trap Trip Trap, on the bridge. Out came the troll, shouting “WHO’S THAT TRIP TRAPPING OVER MY BRIDGE? I’M A BIG SCARY TROLL AND I’LL EAT YOU FOR DINNER!!!”
The middle billy goat replied (his knees trembling a little) “I’m really not much bigger than my little brother, not very much of a meal. Our big brother is coming along, he’s biggest of all, you should eat him.”
“VERY WELL, OFF YOU GO, BUT WHEN YOU’RE FAT I’LL EAT YOU TOO”
The middle goat Trip-Trapped off to join his brother, and the troll settled under the bridge to await his feast.
Later still, along came the biggest goat “BOOM, BOOM” went his hooves on the bridge. Out came the troll, “WHO’S THAT BOOM BOOMING OVER MY BRIDGE? I’M A BIG SCARY TROLL AND I’LL EAT YOU FOR SUPPER!”
The huge goat lowered his head, showing his big curly horns, and replied “I’m a big scary billy goat, and I’ll eat YOU for supper!”, and the goat charged at the unfortunate troll, knocking him clean off the bridge, up into the air. The troll landed with a splash in the rushing river and was never seen again.
The three goats, however, ate the lush green grass and in time were all as big as each other, and they all lived Happily Ever After
