Pipeline Plunge (the yellow enclosed raft slides with the "rainbow" insides), Riptide Run (the blue "wavy" raft slide), and ????? [the individual yellow sled ride which "skipped" across the water at the bottom] (Hydro Force was the OLD name when it was built over the lake, but I'm almost positive it later changed names when it was relocated to Barracuda Bay (though I can't seem to find any reference to a name change with a quick search)
EDIT: Hydro Force was renamed "Torpedo Rapids" when it moved. The Wikipedia / history page is incorrect in listing these as two different slides (also the drop is not 90 degrees )
I wonder what was the name of the slide where the individual yellow sled ride which "skipped" across the water at the bottom?
