You are evil!
I've never played the games so, I look it up on mobygames & the review section on this site, to my surprise I found they are labeled:
Spoiler:Blue Toad Murder Files: The Mysteries of Little Riddle
But it sounds like your going to make me guess the specific episode soooo
I guess 33 to be:
Spoiler:Episode 3: The Mystery of the Concealing Flame
That was a total random guess.
