In Qu's Marsh, you'll see some frogs jumping around. Catching a number of them will give you various items and if you catch 99 of them, you will battle Master Quale( who will give you the Gastro Fork, Quina's ultimate weapon, when defeated). Here is what you get for catching the frogs.

At the beginning of disc three, while controlling Vivi, you can race Hippaul in the streets of Alexandria. Each time you defeat Hippaul, he gains a level. Every ten levels you get a reward. To race Hippaul, you must mash the circle and square buttons alternatively. Every time Hippaul levels up, he gets faster and more challenging to beat.

In Alexandria, you will find a few girls jumping rope; have Vivi or Eiko in your team, then talk to them. They will let you play the Mini Game: Jump Rope.
