Curiosity

here's the conversation when Buzz is switched into Spanish mode:

Spanish Buzz: [immediately after being reset into Spanish, Buzz speaks into his wrist communicator] Bitácora Espacial - Me he despertado de hiper-sueño en un planeta extraño.
Hamm the Piggy Bank: [to Rex] Now what did you do?
Rex the Green Dinosaur: I just did what you told me!
Spanish Buzz: Estoy rodeado por criaturas extrañas y desconozco sus intenciónes. ¿¡Quién anda ahí? ¿Amigo? O enemigo?
[aims his laser at Woody]
Woody: Uh... Amigos! We're all amigos!
Spanish Buzz: [turns off laser and is suddenly friendly] Me debo haber estrellado, y se me borró la memoria.
[helmet still up, he kisses Woody quickly on each cheek]
Spanish Buzz: ¿Han visto a mi nave espacial?
Woody: [dumbstruck] We gotta switch him back.

It is a hilarious scene, I am glad someone wrote it down for you. I don't speak Spanish but if you rent it at Redbox and put the words up on the bottom of the screen you'll see what he is saying even though he is speaking a different language. We always use the subtitles. It encourages the kids in reading and it helps with the volume for those of us... getting a bit older and harder of hearing.

Buzz Lightyear to the rescue?

go to a toy store and push the buttons or look the toy up online it will tell you what it says

Not sure if Buzz actually speaks Spanish in the movie, or whether the toy was programmed to speak Spanish in the store? His main one-liner is "To infinity, and beyond!" Could that be it?

ETA - Go ahead, Denise!!! LOL, BTW, I did see the movie, but only remembered that whole Spanish scene after Denise so perfectly recounted it! :)
