Sock is a character from Drawn to life: The Next Chapter.
Drawn to life: The Next Chapter Edit
Sock is first met, in Watersong, when he tells Jowee and Mari about Wilfre's portal taking him there. They decide, to let him come with them to find his village. Sock usually either chickens out, or runs away, when something important happens. He helps Jowee cope, when Mari goes missing, and helps him find her. When three villages are complete, Sock reveals himself to be Wilfre in disguise, as he also throws away Heather's Pendant. Crazy Barks then uses Sock's hat to get to Wilfre's Wasteland where they defeat him.
Sock may have not been Wilfre's disguise, as he sometimes did actually help the player save the villages
