Yea combined with that dialogue line it looks like a background gag to me
Everyone who complained about Old Ikki proved they're one pump chumps who cum & go. Simply viewing the scene twice will show younger Ikki on subsequent viewings.
For everyone too scared to witness Old Ikki pressing back twice on the Jinora menu, or once on the menu with Pema will increase the variable enough to see young Ikki again.
If you're a super chad who wants to see Old Ikki again, after the two times with Old Ikki the variable that matters is at 27. Clicking "Other Rooms" increments the variable while it's less than 34, and pressing back on the pema menu increments it while it's under 55. If you click "Other Rooms" while it's over 34, it's set to 24 and then you get the appropriate message (Jinora saying "Dad! Please!")
So to recap the new instructions for Spookytimes 4
Look in the bathroom and click on the box at least once before you start the story otherwise you'll be forced to fail with the chat about boobs with the ghost.
(To get the scene the box must be clicked 5 times total at least. You only get the Number Two message once now but it still needs to be clicked 5 times. You can only click on the box when the bathroom is empty, so if the bathroom is occupied for any reason you can't unlock the scene. If you don't have the $5 Korra wants for a blowjob you're actually locked out if you haven't clicked the box enough yet.)
Don't lock yourself out of loli content during the ghost boob chat, say flat is where it's at and then makes no difference
I'm assuming at the end of the story after the box has been clicked 5 times, visit "Other Rooms" 20 more times. If you've done things correctly you should have seen Jinora from the 18th visit onward.
After that follow above instructions
