Werewolf!

My big brother says he saw...

A werewolf in his bedroom
A werewolf at his door
A werewolf in our bathroom
That washed it's face and paws

He glimpsed it in our garage
And lounging on our lawn
On Wednesday night it watched TV
Then disappeared at dawn 

It slyly stalked our hallway
Until my parents SCREAMED!
It crept into our kitchen
Took a tub of our ice cream

It tinkled in our toilet
Then wandered down our road
It growled and howled, made quite a row
While dressed up in my clothes

It stared back from my mirror
But now I'm most concerned
'Cause every time a full moon's out
I grow teeth, claws and fur...
