Knuck Knuck! Who’s Here? is episode 12 of Season 2 of Sonic Boom, the CGI comedy series made by Technicolor Animation Productions with Sega of America. It premiered in the United States on 28 January 2017 on Boomerang.
Synopsis

A Sonic-assisted launch into a boulder leaves Knuckles with amnesia. His friends’ cure, plus a scare from Sticks and a barbell to the head, brings his memory back with an odd side effect: for the first time he is thinking clearly, and he understands what being the last echidna really means. So he sets out to get himself adopted.
The applicants aren’t promising. Mrs. Vandersnout only wants someone to fetch and carry, and soon trades him in for Dave the Intern. The Gogoba Chief rejects him for being helpful, then guilt-trips him into moving a boulder anyway. Lady Walrus takes him on as the daughter she always wanted, dress and all, until he fights her son over a Meh Burger toy.
The family that finally says yes is Charlie and Belinda, who plan to use his loneliness to turn him evil. After a montage of kites and barbecues, Knuckles brushes off Sonic’s warnings and joins Charlie’s mech suit in an attack on his friends, until Charlie, using him as a human shield, snaps and admits that Knuckles is being used. Knuckles flips the mech, the villains flee, and Team Sonic shows him where his real family has been all along.
