Super Mario RPG Monster List - How to fill out the Monster List and where to find every monster

One of the new components of the 2023 remake of Super Mario RPG is the inclusion of a Monster List. This list is practically like a classic RPG bestiary, and it lists every monster in the game once you've encountered them in battle. You may be on this page because you want to complete this list.

There are two components to the Monster List.

1. The first is simply having the monster appear in the list, which requires you to meet that monster in battle at least once.
2. The second component is if you have the "Thought Peek" information for the monster, obtained by using Mallow's Thought Peek ability.

Now, while several monsters in Super Mario RPG may seem to be 'missable', in fact, nothing about the Monster List in Super Mario is actually missable.

The new Switch version of Mario RPG goes easy on players with elements like this, just like how none of the Hidden Treasure Chests are missable. It's important to note that once you clear the game and see the credits, the game will automatically fill in every missing monster in the list. This means that, actually, you don't need to worry about missing monsters during your playthrough.

As for Thought Peek information, this is not missable either. You can get this information by having Mallow use his Thought Peek ability on any monster, regular enemy or boss alike. If you miss Peeking on a one-time-only enemy - don't fret - there is a new NPC in Booster Pass who will fill out Thought Peek information for the price of 3 Frog Coins each. With Frog Coins now being much more available in the remake, this functionally means you can just buy your way to a full and complete Monster List, although it is much cheaper to have Mallow do it himself.

With all that said, here's the list of Super Mario monster locations. The list is in the same order as in the game.
