We haven’t done a Backyard Picnic start yet. It ends with Ariane in the backyard in a swimsuit.

This path is available in the help section of the game. On the main menu click “Help” then click “Paths” on the top row, and next to where it says “Pool Hijinx” click “Enable”, then load up a save of “Backyard Picnic”. Correct choices will be highlighted in Magenta. Note: Where there is more than one choice, you might have to do one, then the other when you get to the choice page again. If you did not save an opening, enable “Backyard Picnic” as well and start a new game from the beginning.

First I am going to show you something rare.

Go to the pool
Go Swimming again
Try to untie her bikini top

Most people never try this assuming it ends the game but under the right circumstances it is a doable move. The dialog in the section differs if you are playing as a male or female. Ariane steals your shorts if you are male, and your top if you are female.

Keep her top
Keep her top
Knock on the gate
Threaten

How to win or lose a swim race:

Go to the pool
Go swimming again
Swim some more
Challenge her to a race
A
B
C

The time in seconds between clicking A and C determines outcome, if less than 2 seconds you will lose by running out of breath, if more than 2.5 seconds, you will lose by being too slow. To win you have to time your clicks between 2 and 2.5 seconds.

Click whatever comes up until Ariane laves the pool.

Go inside and shower off (this may not come up if you followed this path exactly)
Wait in the hallway (if you lost the race)
Follow her into the bathroom (if you won the race)
