From Tigger's mini-game go to the back of the forest and take the path that leads to the muddy area (the place where everyone had to be escorted into the reeds back in KH1).
You'll find a well and if you jump into it you can launch yourself into the sky to start a free-falling game.
This one is a little difficult but only because you MUST be holding Pooh or you can't collect the coins.
As you fall you'll find hoards of coins in various shapes and sometimes even making "tunnels" to travel through and all you need to do is pass through them to collect coins.
However there are trees, logs, beehives, and other debris that will cause you to lose your grip on Pooh instantly. Should that happen you must catch him and press
to get him back.
You can also roll with the left analog and
to dodge debris quickly.
Collecting the large coin at the end, again, is a must for the 2000 points. I got just over 2010 points because I lost Pooh twice but that big coin is worth a tidy sum.
