That's a good idea, I like it. There is a little bit of downs and ups about this idea though. Talking about the downs, as stated above, trolls might pick you up and carry you somewhere where you don't want to be carried. And also, Kovu has the codes so I don't think that will be possible to add this idea into the game without Kovu.
I have some ups here. An option that a member stated above to stop the problem from trolls randomly picking you up, when someone tries to carry you, you have an option to decline or accept. If you accept, you'll be carried away by the person and If you decline, nothing would happen. To not bother people, the option might be located somewhere at the top. You don't have to accept or decline, you could just leave it as it is and continue RPing, not a problem at all. The idea is really good but unluckily, Kovu didn't return to Feral-Heart, YET.
