I've been playing a lot of Dynasty Warriors 4 lately, and I was beginning to wonder how to get the saddle items.

Turns out there are a lot of requirements for some of the items, and mostly by doing quests in certain manners.

Eg: Apparently to get Red Hare, you have to play in the Cao Cao missions up to the level where they are crushing Lu Bu's fortress. Then you have to go directly to it (south-east corner), and kill 100 people by running over them without hitting any of the attack buttons...
