Sam & Max

You'll get this as you progress the story, at the point you open the backup secret tunnel.

Another story related one. You'll get this after taking control of the clones, following them and witnessing the reveal.

Finish the episode.

Story related, you get it once you have gotten Stinky and Sal hypnotised, the DNA sample from Momma Bosco, and the parchment from Norrington. In any order. Note that you don't need to go through every optional dialogue option, just the important ones.

Simply requires a bit of logic to the trial and error. Go on a trip without changing anything, note down the results. Alter one dial and go on a trip, note the change. Make that dial correct. Alter second dial go on a third trip. Correct it. Alter third dial for the fourth trip. Correct it. Alter fourth dial for fifth trip. Correct it. Go on sixth trip with correct combination. You will likely accidentally get the right combination earlier but this method will guarantee the trophy.

Use the Mind Reading ability on the newspaper stand at Sal's new job.

Takes an entire playthrough of the game, you need to use the dummy on everything as often as you can.

1. Use it in the Diner before solving the cake business.
   1. Doppelgangers at window
   2. Granpa Stinky
   3. Flint Paper
   4. Stinky

2. Use it at Sal's new job before solving the cake business.

   2. Superball

4. Use it in BoscoTech after finishing the seance.
   1. Momma Bosco
5. Use it in Paiperwaite's office.

Some of these may be redundant.

There aren't that many things but most are missable. During the end fight you need to make Sam change the song to all four options and read his mind each time.

1. Stinky's Diner - DeSoto
2. Sal's Job - Cake
3. End Fight - Charlie Ho-Tep
4. End Fight - Darkness
5. End Fight - Fire
6. End Fight - Grub

Just like Sawdust Laryngitis this will take the whole game and can easily be missed.

Shoot at the massive cave of cloning pods repeatedly until you get the trophy.

This one involves finding a lot of references to previous games and some classic adventure games.

1. At the very start, talk to Skun-ka'pe several times until Sam offers him some Banang.
2. At any point before taking control of the clones, talk to Max and choose the Random option several times.
