dream park boat ride with various animatronics inside. like the animatronics in the hotel one of them (but only one) gains sentience. it becomes sentient while the park is closed for the night. it's alone for several hours. it's a fairly rudimentary animatronic so it only has a limited movement. it COULD have an audio track to manipulate and use to speak but i'm not sure yet. it might just be silent. 

it's lonely. none of the other animatronics are sentient. it has a very human understanding of what it sees but isn't able to interact with anything. when guests start coming through the ride it becomes excited! if it has an audio track it would try to communicate and speak with guests but this would probably put people off. if it doesn't it would only be able to communicate through movement and nothing else. desperation would set in the more it gets ignored. this animatronic is only supposed to be something to view. perform its movements through its preprogramed movements and nothing else. it can think. it can feel. it wants to interact with someone. 

i think dream park employees would be freaked out by this occurence. if it can speak it would be noticed earlier but it would also scare the employees at the ride a lot more. which would hurt. i think. to be able to speak and want and only be met with fear or ignorance. 

if it can't speak.. it would take them a long time to notice. the desperation would set in. its movements have gotten increasingly intense and it is wearing itself out. this would likely be the first time it gets full attention on it and it would be met with a horror. a dawning realisation of how long it's been like this. sentient without anyone to talk to. whatever the situation is. 

i think one day the ride would reopen as usual and the animatronic is either 1. just gone. no explaination. or 2. it's there but no longer sentient. it's motions have returned to normal and there is no sign of life behind its eyes. the ride is back to normal
