Brownie with a Whistle

Upon a hike in the mountains
There was a girl with a whistle
She was a Brownie, so the whistle was quite useful.

While she walked with her fellows
And played with her whistle,
She ate a pack of marshmallows,
As she got her hair stuck in some thistles

As her friends moved on
Singing a song
She blew through her whistle
At her friends dismissal,
Meaning she needed assistance

Friends came to her aid
To help with the problem she'd made
After, they shouted 'Hooray!'
And continued on their way
