WTF is this?!

YouTube - Final Fantasy 7 Battle Jumbo Cactuar

Some of its attacks do 32,000 damage! Man. It looks scary!

I took a lil' visit to Cactus Island myself, after watching the video, but after a while of running around, I never managed to get into a battle with the Jumbo Cactuar. Has anyone ever beaten this thing? Or know how many HP it has? Or if you get much EXP/AP for defeating it?

There was no info in the 'Enemies' section on this site.
