If there will somehow be a Toy Story world, then one of the items should be something that summons the Steadfast Tin Soldier and Ballerina. I'd imagine that the Jack-in-the-Box would be an optional boss that you'd have to battle and, after beating him, you'd get the aforementioned item.
Byzantinefire say what you want to about such cast, There are ways Toy Story could actually fit such video, and there are ways harmony is clear on Wikia's wikis. The characters like Woody are loyal enough to help Toy Story's cast join Kingdom Heart. I even daydream of Woody being my watchful soldier when I dream of having my own kingdom, and I also dream of riding Bullseye with Woody, plus there are several places Woody could live or go on vacation too these choices include Australia and South Africa. Woody's loyalty is misunderstood by some people, but Rafiki's loyalty is misunderstood at a worse level. Woody's not murderous like WeedleMcHairybug says. Woody's considerate about his friends, while Rafiki's humble about the hero within himself.
Woody's loyalty shows several ways, as a toy he just needs to be studied more closely
He teaches Sid about harm
He teaches Buzz Lightyear about the importance of being yourself and accepting what you are
He saves Jessie and he tells her enough to comfort her
He's a true friend of Slinky Dog's
He'll keep self-controlled even with those like Rex
He likes being helpful especially to friends like Bo Peep
He cares about how Andy feels
He's loyal enough to let Bonnie's wish of keeping him come true
He's protective when his friends face characters like Lotso
