Hello!
Here I want to share my experience in achieving the most difficult achievement in this game!

!!!!! YOU NEED TO BE READY TO DESTROY YOUR PARK AND BUILD A NEW ONE FOR THIS ACHIEVEMENT !!!!!

What do you need?
🟢 Maximum park level
🟢 Inventory such as a leaf beater
🟢 Free time and desire)

Step 🟢1
- Completely clear your park area so that nothing prevents you from building a new one
Step 🟢2
Fire all the cleaners, you don't need them anymore
Step 🟢3
Place 3 large pools as close together as possible
Step 🟢4
Place as many sun loungers as possible as close together as possible to get the maximum number of visitors (100).
Step 🟢5
Set up hot dog/ice cream/lemonade shops as close to the pool as possible and hire 3 salespeople to sell them.
Step🟢6
Place vending machines with food and soft drinks as close as possible to the pool, 3 or more of each, as close as possible to the pool.
Step🟢7
Your task is to make the park as compact as possible. To do this, place the yellow wooden fence, which can be found in “Decorations,” as compactly as possible to enclose the park.
Step🟢8
You can start your “Poops Land” and wait until the park becomes as dirty as possible. You should not have any toilets, trash cans, or anything else, so users have nowhere to go to the toilet and all the poops will be everywhere, especially where food is sold! Now it's time to put all the poops in your park into the pool!

To do this, you can use your hands (hit) or a leaf beater to blow it all into the pool! You don't need to clean the park, your task is to start the park and watch as everything turns into poops and then drive it all into the pool!
Then just vacuum it all up and get your poops in the achievement progression!
There can be 10-30 poops per game day!
The only staff you need are a stock replenisher and a repairman, make EVERYONE ELSE a salesperson!
Good luck! It took me 3-4 hours of calm gameplay to achieve this.
