Scritchy Scratchy Mundo Guide

Scritchy Scratchy starts as a simple lottery game. However, it quickly turns into a complex automation puzzle. Many players unlock Mundo and wonder if this robotic cat is actually worth the investment.
Mundo is a background helper who scratches discarded cards. He is incredibly slow at first but becomes a great tool in the late game. I will cover everything you need to know about this cat and his related achievements.
What we cover here:
How Does This Robotic Cat Work?
Most players expect a huge speed boost after buying the cat. That doesn’t happen. Mundo acts at his own slow pace. He picks up leftover tickets from the scrap bot and scratches them for you. Here are the core mechanics you must understand:
- The cat works entirely in the background.
- He processes cards much slower than your manual clicks.
- He will never complete a grand prize or super jackpot. He tosses those valuable tickets back onto your table.
- You must manually finish the winning tickets to claim the cash.

Is Mundo Actually Worth Using? (Pros and Cons)
You might feel tempted to ignore the cat completely. Early in your playthrough, he feels inefficient. However, community discussions and late game testing reveal a different story.
| Pros | Cons |
|---|---|
| Automates basic scratches | Extremely slow early on |
| Crucial for specific achievements | Leaves grand prizes unfinished |
| Trashes negative tickets later | Can bankrupt you if ignored |
The Hidden Late Game Strategy
This is where many beginner guides get it wrong. They call the cat useless. However if you invest in the prestige skill tree, Mundo becomes incredibly powerful.
After you die a few times and earn prestige points, you can unlock a specific upgrade called picky eater. It costs 250 JP. This upgrade allows the cat to trash bad tickets automatically. Suddenly, he is no longer just a slow scratcher. He becomes your safety net. He handles dangerous items like the apple tree so you don’t lose your hard earned quintillions.

The Permanent Death Danger
You need to be extremely careful with a specific late game event. The game can actually kill your robotic cat forever during a playthrough.
This disaster happens if you let the cat touch the Final Chance ticket. Sometimes the fan can push this item directly into his workspace. The cat will process it and the game will instantly delete him. The shop will block you from buying another one until you restart. You should always lock your valuable items down on a mat to prevent this.

How to unlock the Bad Kitty
This achievement forces you to make terrible choices. You must allow the cat to completely drain your bank account to zero. Since he works slowly, you have to set up the perfect trap for your own wallet.
| Step | Action Required |
|---|---|
| Skip Picky Eater | Make sure you ignore the Picky Eater upgrade in the skill tree. |
| Borrow from Corporation | Accept three separate loans from the company to ruin your financial backup. |
| Halt Economy | Stop buying any upgrades that increase your passive income. |
| Lower Luck | Keep your luck stats as low as possible. |
| Feed Bad Cards | Force the cat to scratch risky tickets like Lucky Meow. |
| Wait it Out | Take your hands off the mouse and watch your money disappear and your balance drop below zero. |
How to unlock the Good Luck
Many players struggle with this bug. The goal is to hit a jackpot on your initial scratch of a new game. You can easily manipulate the rules with a clever trick.
Begin a new playthrough and process only plates through your bot. Allow the cat to gather the money from these plates until you can afford the expensive 5k Luck upgrade. Buy one cheap card and scratch it yourself. Restart the entire run if you fail and it is not a jackpot.
FAQ
Why did the cat stop scratching my jackpot?
The game intentionally programs him to stop. You must always finish the big wins manually to prevent accidental discards.
Can I speed him up to match the scrap bot?
No. Even with upgrades, he will never match the raw output of the main bots.
Is he required to beat the game?
He isn’t necessary for the main ending. However, you absolutely need him if you want to unlock all achievements.
