Vendraxoo
From Tardis Wiki, the free Doctor Who reference
The Vendraxoo were described by the Eleventh Doctor as a "nasty bunch". These wrinkled creatures once attempted an invasion of Earth from their ship buried deep inside the Alps but ran scared when they believed they were to be attacked by a giant snowball. (The giant snowball was actually the TARDIS covered in snow as it rolled down the mountain.) The automatic defences of the Vendraxoo spacecraft were activated to avoid the collision and the Vendraxoo threat to Earth was cancelled. (COMIC: Snowball!)
