I gave my son a copy of the Choose Your Own Adventure about the UFOs for Christmas a couple years ago. It's the one with the impossible ending. The only way to get the good ending is to cheat and flip to it.
I also wrote a hidden message in the picture in the hidden ending. He still hasn't found it.
OH MY GOD I REMEMBER THIS ONE.
I remember going back and following literally every single possible story path and never making it to the planet Ultima. And then going through page-by-page until I actually found it.
That's wild, this must have been about 20 years ago. Thanks for reminding me of a childhood memory.
