Are are quite descriptive in that post there...I could draw a picture from all the details you provided for us...
Well out of my knowledge (which has been contradicted several times...lol) I gather this:
Typhoon Lagoon doesn't have any "really big" slides...so I assume your post is only of your own speculation...lol. However, there are slides...one being Humunga Kowabunga.
Yet maybe you are referring to the water coaster...Crush 'n' Gusher...
Other features include Keelhaul Falls, Mayday Falls, Gang Plank Falls, Storm Slides and then some pool features such as Shark Reef, the Ski Patrol Training Camp and the famous wave pool...
