Yule Lad #10 Window Peeper

Window Peeper is a weird little twit who peeps through your window and may try to steal your stuff if he likes what he sees...

The tenth was Window Peeper,
a weird little twit,
who stepped up to the window
and stole a peek through it.
And whatever was inside
to which his eye was drawn,
he most likely attempted
to take later on.[1]
