👃Smell You Later Puzzle Train!🚂 [How to solve added] last day

Welcome to the 👃Smell You Later Puzzle Train!🚂 I was going to call it the Final Puzzle Train, but I might make another one someday-just not anytime soon since I have different ideas to try out. So, it’s not really final, more like smell you later!

Each main train giveaway features full cv games (well, they were when I made them—who knows now?), and each cart comes with a bonus puzzle giveaway. The puzzles are ones I’ve used before, so if you solved them before, this will be a breeze. If you couldn’t, consider this your redemption chance!
