Toy Story 3

> Alien 1 (Prisoner): Found on Level 6 "Prison Break / Hide and Sneak"

After hitting the switch to rescue Jesse, continue to the back of this room - the Alien is in the back corner.

> Alien 2 (Zurg):- Found on Level 7 "Junkyard / Trash Thrash"

After saving the 3 Aliens, and dodging the Crusher as Buzz, you end up controlling all 3 characters in turn through a set of air ducts/platforms/pipes.

As Jesse you will be required to Jump and land on a switch that activates electricity to open a black & yellow floor/roof section. Switch to Buzz and wall climb up through this newly opened section. Pick up the two cubes/blocks & destroy the two fans for Woody. Then pick up a third block and move to the right, where you do a small jump down onto the platform at a slightly lower level.

At this point you drop the block to the level below (pipes) for Jesse. Switch to Jesse, jump up on the block, then pick up the Zurg Alien.

(If you move on too far with Buzz, you will not be able to go back and drop the cube/block to Jesse, so she will not be able to reach the Alien)

> Alien 3(Witch):- Found on Level 8 "Haunted Bakery / Muffin to Fear"

For me, this alien just appeared in the middle of the main street (where you initially start the level) as I was blasting the first wave of Muffins & buildings - I don't believe there is a specific trigger, and it should appear for everyone.

Please add a comment if you believe there is a specific trigger.
