Regarding Timmy, the Companion Cube from the game Portal is the greatest example of induced anthropomorphism that I've ever experienced. If you know, you know, and if you don't, you should really play the game, since it's brilliant.
It is a brilliant game and the empathy you develop for the cube is a great concept.
But arguably much deeper is the fact that nothing in this game, or any single-player game, is a living thing in any form. Arguably the game's characterization of GLaDOS hits even harder on the anthropomorphism angle.
That's a matter of informed anthropomorphism. A lot of people don't become attached to the Companion Cube, but are informed that their player character is so attached.
