I have organized this guide by day. Most days will follow a mission, which I will not be discussing in detail. If you want a guide to help you complete missions please see "Kindergarten 3 - Full Game 100% Guide" by JokerFactor. This guide is focused on routing Monstermon into an efficient speedrun. In this guide I will list all of the Monstermon to get in a specific day, I will explain when in the day you should get them, and what you need to do to get the Monstermon.

If I do not list a section of the day, then there are no monstermon to collect in that section. Just follow the mission as normal.
Note: Not all of the monstermon have to be collected when I say they should, or even in any specific mission. This is my personal guide to route all of them in as efficiently as possible. If you have any ideas to adjust or streamline this route, please let me know!

Ms. Lovelett's mission contains nine Monstermon cards we need to collect.

Morning Time
1. As soon as you can leave the classroom, do so. Head to the front office, stand on the pit, and eat apples until you fall down the pit and die. For this you get Chair of Spikes
2. When you take Guppy out of the fishbowl, do not give it to Davey yet. First try to put it back in the bowl to get Dumb Fish
3. STILL do not give back Guppy, instead head to the bathroom and try to flush Guppy down the toilet to get Petty Piranha.
(Now you can give Guppy to Davey)

The Janitor's mission is really easy! It only has one Monstermon, which is for completing the mission.

Completion
1. For completing the mission you receive Frowny Frog.

Davey's Mission has four Monstermon.

1. While in the cafeteria, grab the ketchup bottle on one of the tables. Then continue the mission until you get seen by the Nurse and kicked out to the front office. Then head to the playground, pick up a rock and break the back window. Jump into Scippio's classroom and feed him Ketchup for Mystical Tomato. Reset Lunch
3. (Step One) This time you play through lunch, head to the Janitor's closet BEFORE you head to the nurse, and grab the note from the trashcan. Then head to the nurse, and return to the cafeteria. Then talk to Monty and get him to read the note.

Recess

Felix's mission has six Monstermon to collect this day. However, Felix's mission is special in that it contains two possible endings, and each of these endings rewards a different Monstermon. As such, we will have to replay Felix's mission a second time later in the run.

Morning Time
1. Interact with the Applesoft package to get Mysterious Package.
2. When Lovelett is on fire, walk into her to die and get Man on Fire

Lunch

Recess
3. After Applegate leaves the room on the phone with Bob, walk into the cafeteria to listen to them. You have to walk out there three times. On the third time, Applegate will give you Hearty Heart

This day is completing Felix's mission a second time to get the other completion Monstermon.

We will also get one other Monstermon today.

Your Bedroom
Before starting the day, you must grab the Vent Map.

Before School

Then reset the day

We will grab two Monstermon today.

Your Bedroom
Grab the Gator Nugget and head to school

1. Head to the underground lab and step on Kevin's hay to get Bullzerker

Then reset the day

1. Look for monsters under your bed to get the final Monstermon, the Slurpolotl.

Now you can pay attention to the glowing rug and reach the final ending of the game.

- Use the dialogue skip key as much as possible, but be careful not to mess up a dialogue tree. Sitting through a bit of dialogue is much faster than having to reset a section of the day.
- Know what items you need for each mission (Including the additional items I mention for Monstermon on specific days)
- Know what to do and where to go to complete the missions. This should not be your first playthrough of the game. This guide is for speedrunning. The game contains lots of fun and hilarious dialogue and secrets that you should explore for yourself. Then, you can come back to this guide for another time through.

Finally - If you notice any mistakes I have made in creating this guide, or changes that you think would make this speedrun route faster, please let me know! This is a very early route and still a work in progress.
