Rhyming couplet poems are prolific; we read lots for laughs and then looked at whether we can spot rhythms which sound best and why (tip: if the number of syllables is one different between the two lines it doesn't tend to flow).
W comes up with the name and K sets up the back story. W questioned K's premise throughout - why would a boy who is teased for having huge eyes be mean to animals? It's a leap, but I like K's logic that the big eyes hint at what might become of Billy later.
They managed to include an onomatopoeia (W's new favourite word!) with 'whizzed', rhyme, some sense of rhythm and alliteration (big brown bear).
A true team effort, here's the finished poem :
Silly Billy
There once was a boy called Billy
With big eyes which looked rather silly.
Because he was bullied by everyone
He started to hurt animals for fun.
At the zoo he stole a small giraffe
Then had a laugh when it took a bath.
In the woods he caught a big brown bear
At home he shaved off all its hair.
Billy took his neighbour's snake
And baked it into a birthday cake.
In the desert he found a cheetah
And roasted it inside a heater.
He woke one morning, my oh my,
Billy had turned into a fly.
As he whizzed around the ceiling
Billy got a sinking feeling.
He tried to find a way to flee
Bu a spider ate him for its tea.
