Welcome to the Most Efficient Guide for All 50 Monstermon Plushies in Kindergarten 3! 🧸

This guide walks you through the fastest possible route to collect every plushie with the least amount of repetition. It’s structured around mission order, item dependencies, and death-trigger unlocks, so you’ll never waste a day or do unnecessary steps.

Whether you're aiming for 100% completion or just love collecting cute murder monsters, this guide will get you there with maximum efficiency and minimum backtracking.

I have also made a YouTube video for those of you who'd like a visual guide, which you can find right here

For most sections in this guide the first step is done inside your room (I believe there are only 2 exceptions) I will not be including this in the guide, simply read the first step before you leave for school to determine if you need to do it in your home or not.

I have added the mission requirements and rewards to each section. I also include a step to grab the requirements. Anything I grab that is not listed in the requirements is needed for a monstermon plushie.

This guide contains:
✅ Optimized route
💀 Deaths included (on purpose!)
🎒 Mission requirements tracked

You'll also need to pick up a plushie you couldn't get earlier due to not having the needed item yet.

And there you have it, the most efficient (that I could find) route to all the plushies, there are some plushies that can be aquired through multiple ways or in multiple routes, I simply added them at the first available option with the exception of the plushie hidden in the tree. In the tree you can get 2 plushies technically, however the first time we visit the tree you wouldn't have the opportunity to get the second plushie, so I grab that plushie a little later when the tree is visited again.

Personally I would have liked to list all the plushies to get per mission however I want to get this guide out as soon as possible and I'm running out of time to work on it, If you can make that list I'd greatly appreciate it and be sure to give credit otherwise you'll have to be patient for me edit this guide with the full list.

And with that said, please feel free to give me constructive criticism, Please consider rating this guide and I hope you enjoyed the first guide I ever wrote.
