However, when a tiny piece of crystal lands in the hot spring, it creates a 'fountain of youth' which the animals then bathe in to regain their youth.

Also, how is Brook able to leave the fountain of youth and go looking for Sid at the end of the movie without growing old?

Later, a truck passes by, and the salesman does the same thing, but the message is now in Spanish, without the man stopping to change it.
