I could fit in to the animals theme... "Journey" is a ride about how you're part of some scientific team (Captin Nemo's, not the fish!) that are trying to find new plant species ( glow-y mushrooms, etc.) and animal life (there are some glow-y animals there too. Like little tiny glowing bugs) in the center of the earth. That's why (you can see this in all of the shizzey online videos) they're all marked with little tags and signs. Then of course you go off the track and "something goes horribly wrong!" You go past parts of the center of the earth never seen before, and therefore they don't have little signs from now on. There's a canyon of lightning in the distance and a lightning bolt even almost hits you! Then, coming up to the biggest "animal" in the ride, there's a blast of fire. You turn that way and you hear a loud, peircing screech on the other side of the vehicle. It's a ginormous lava monster! You hightail it out of there, following an upward path (you ARE in the center of the earth; the only way to escape is up!) and you finally burst out of the mountain!
The subs are pretty self-explanitory in the animal department, of course there are fish, the squid, and in the version ot TDS, a huge city of mer-people that help you ecsape the wrath of a sea creature!
Or what jt04 said.
