The folks at NinjaBee say it can be done by going to the pool, getting stinky, crossing back over the clean water (without getting in) and presenting yourself to the guys who sent you down. It just wasn't happening for me.
Well, there is another way...
1. Kick the guy who tells you that you smell "pleasant" twice in the direction of the altar (the one where the perfume opened the gate).
2. Kick the guy who sends you to the pools twice in the same direction. The second guy won't be quite to the left of the gate, but he'll be close enough.
NOTE: If you kick either guy 3 times, he dies and returns to his original position.
3. Go to the stinky pool and hold your character to the bottom until he dies. Your character will come back on the shelf just above the 2 goofy guys you met at the beginning. Make a mad dash to the right and you'll get to the "You smell pleasant" guy just in time.
Yes, I know that won't give you 100% but it sure beats giving up on the game like I almost did. I will revisit the level later.
