I figure this is closest to the topic of mounts, I was thinking it would be fun/funny if there was an item that would allow me to jump on the back of any creature bigger than a certain size and ride it. More like the pig saddle from minecraft than an actual mount in the sense that I have no control of its movements. Except I don't want to have to find another of the item each time and it would be fun if it was any creature I could find (or other players too) instead of one creature in particular. Aggressive creatures could go berserk and start running everywhere while passive creatures are more likely to go about their day as normal. Too big/too aggressive and you get flung off, hurt, and possibly mauled. Too small/too passive and it just flops to the ground (they'd get up if you weren't on top of them).
True, and I didn't think of that. was just throwing the idea out there while it was still fresh in my head.
