change dodo skin
You can't actually change the skin of the dodo in LU unless you use mods, but then even if you did it'll only be for the client and not for the whole server.
enter in helicopter and use map editor to move
I think that this is possible but a lot of work will need to be done, helicopter speed, elevation, object moving etc, however the object would be server side and players with higher pings (me :p ) may see the object being moved a bit behind time. Moving the helicopter object might also cause server lag since it has to be moved many times and tons of calculations have to be made.
