i think the underground train should be no problem, i saw it often in hacks where you can choose, where you want to be warped (the last one was underground i think) so you can activate this script by talking to a man for example like in G/S, i can do an OW which looks like a train (did you see the planejet in Zephyr? i made this sprite)
about the "teleportion"-script, dartharon, any idea how to activate a script with an item?
and like i said, it should be also a pokemon, so the item looks like a pokeball with a wing or so on (i could make that sprite if you want) and so we can leave the animation of fly like it is
BTW: Zetka, this is a really good sprite, i see, i teached you well xD the only thing that you should change are the hair, because you couldn really see that thease are hairs, you see the hair next to his face and next to his ears? thease hairs are brown, you should change it to the blond and another tipp, use a darker yellow (like the shadow site for the t-shirt for example) to...ehm...umranden the sprite xD But very good! ^_^
