“Eye-spy with my little eye”

“Eye-spy with my little eye something beginning with B”
So they all looked around and about wondering what she could see
As the small girl giggled saying
“Do you want a clue ?”
when her brother belted out 
“Is the answer blue ?”

“No silly billy blue is wrong, you cannot say a colour” as she scowled so strong
Then her sister shouted “B for boat ?” as she did yearn
“Yes youv’e guessed it right now it’s your turn !!”
