An Embarrassing Incident

Objectives
Look for Vic's Keys inside the lake at River's Heart. Provided Item:
 * Vic's Keys
 * Vic's Emergency Air Tank

Description
There's one little problem we have to solve before we head out. You see, I can't seem to find the keys to my flying machine.

I've looked pretty much everywhere for them... maybe you can give me a hand. Only place I haven't looked yet is inside the lake.

I'll even give you my very own air tank. It's almost empty, but it's got a couple of hits left.
