Walrus is the name given to a character from Vinny's stream of Tomodachi Life. His catchphrase is "Goo goo gjoob", referencing The Beatles "I am The Walrus".
Walrus was first in a relationship with Two-Faced. Vinny despised this, but ended up feeling bad for Walrus when the two broke up.
Alpaca was his second relationship. This lasted for a while, but eventually Walrus had to raise the baby by himself.
