Call of Duty: Modern Warfare 3 Easter Egg - A List of More Teddys I Found

All these will use the same technique, being going into a private game and going into free spectate...

Seatown:
You can find a well at the southern most part of the map. The teddy is within some rubble at the bottom.

Dome:
Go to the bottom entrance of the large building. Go inside and immediately to your right into a ruined room. The teddy is under the desk in front of you.

Arkaden:
Go into the largest portion of building and locate the burger joint. Fly over the counter and through the window. Finally, turn left.

Bakaara:
There is a square portion of area on the top of the map. Go into the small building just to the left of that. It is a 2-room building. In one room on the floor is a torn-up teddy.

Bootleg:
There is a square-ish building on the right side of the map. Go to the top and look towards the center of the map. Look down and fly to the first lit level below you. You will see a teddy in a chair in front of a shut-down television.

Village:
In the top left part of the map, there's a building connected to the edge of the map. Go there and there will be an open doorway on the top level. Go in to see teddy.

Another on village:
At the very bottom left of the map, in that small building there will be a washing machine next to an arcade machine. The teddy is on the washing machine.

Mission:
In the Northern part of the map, you want to go to the square building in the center of the north. Go inside the upper story and go left. You will find a teddy, "Porter was here", and a hand-painted drawing.

Porter is the man that lost his daughter in the making of MW2. Her favorite toy was the teddy bear. So, he put many teddy bears in the following Call of Duty games after her death, to remember her life. We can also infer that she painted the picture.
