Eet's-a Me, Calamario!
Game: Assassin's Creed II
In the last chamber of the Santa Maria Delle Visitazione, there is a pool. Stare into the pool for one minute, and a SQUID swims by. Repeat the process, and an enormous tentacle comes out of the water. Yeah, we don't get it, either. Unless Ubisoft Montreal is making some kind of byzantine penis joke, in which case *applause*.
