Okay this is just a suggestion because i was thinking about this and i thought it would be really cool to have. Here i go:
Well, there are bikes and such in the Pokemon games. I was wondering if there could be a /bike command. It would cost 2k or be a donator perk to get the bike command, and not be able to be used inside buildings. Here is how it could work:
By using /bike, a you automatically start riding a horse. Horses cannot ride inside buildings in vanilla Minecraft anyway, and this could be a cool way to implement Pokemon bikes to Minecraft with the help of horses. The horses despawn after getting off.
This is just a little thought I had and i hope you liked it!
