I found this on my wall this morning.. Something was growing out from the wall!!!

By late morning it had grown to this and it migrated to the armrest of my chair..

And then by late afternoon it had grown even longer and hopped to the table!

What is this mysterious strip of thing that keeps growing and moving around??

Is it a tempura or lollipop for me to eat?

Is it a wand for me to be Harry Potter and cast a spell on you?

Or was it Santa's moustache he left behind last Christmas?

Make a guess! What is this???
