ZZZ Top 5 "Most Uncommon" Achievements - 99% of Proxies Missed Them!

by ZZZLucien 08 Feb 2026

Let's break down the most difficult achievements to complete. As of the current version, Zenless Zone Zero already has 627 achievements, including several memorable and extremely uncommon ones. Today, we'll go through a few representative achievements together. See if you've completed any of them!

1. Achievement: Noodle Connoisseur

Difficulty: ⭐️

Zenless Zone Zero Noodle Connoisseur

The requirement is to eat at least one bowl of each noodle flavor. Since the noodle effects only apply in daily instances and HDD, most players don't go out of their way to eat them, let alone try every single flavor. Additionally, buying all these noodles costs a lot of Denny. In a way, this can be considered quite an expensive achievement, and very few players have completed it.

2. Achievement: Path to Simplicity

Difficulty: ⭐️⭐️⭐️⭐️

This achievement requires clearing floor 50 in any Battle Trial without using Special Attacks or Ultimates. However, since this achievement is tied to the title [Pure Strength], it has gained some popularity and is slightly less obscure. As versions update and stronger characters are released, this achievement will become increasingly easier to complete.

3. Achievement: Good News! We've Got a Cat!

Difficulty: ⭐️⭐️⭐️⭐️⭐️

ZZZ Good News! We've Got a Cat!

This achievement features an extremely lengthy process. Completing this series of achievements without a guide takes several (real-life) days, involving tasks such as debugging time, finding the cats, identifying patterns, understanding cat language, and correctly choosing whether to feed or pet the cats—as well as deciding whether to feed them together or only feed "Inky". In earlier versions where time periods couldn't be freely adjusted, the difficulty of this achievement was even higher, earning it the reputation as one of the "hardest achievements to obtain."

Fortunately, after completing the series of tasks, you can take the little black cat home. Remember to pet and feed it cans frequently at home, as there are follow-up achievements and Polychrome rewards for doing so.

4. Achievement: Sixth Street's Lord of Shadow

Difficulty: ⭐️⭐️⭐️

ZZZ Sixth Street's Lord of Shadow

Besides Inky, there's another kitten on Sixth Street named Cookie. There's currently no clear method to obtain this achievement. The most reliable way is to interact or pseudo-interact with it during different time slots (in-game time) from Monday to Sunday, for a total of 28 times. The main challenge lies in finding the cat.

Cookie may appear on car roofs, rooftops, lampposts, roadside, back alleys, and other locations. Sometimes it can't be found because its spawn is occupied by a character affinity event. In such cases, you either wait for the event to refresh or have to wait another week. The subsequent dialogue achievements, however, are much simpler.

5. Achievement: Before the Last Stand...

Difficulty: Unmeasurable

ZZZ Before the Last Stand...

When the movie with the most Easter eggs, "Ready Player One", hit theaters, some claimed they easily guessed the final Easter egg was driving backward, but most people only said so after watching it. It created an expected-yet-unexpected moment for many. It must be said that the designers were quite clever.

After completing the challenge of floor -1, you can obtain this achievement. The challenge process is very interesting, with Easter egg voice lines poking fun at the then-meta characters Caesar and Miyabi. Revealing the unlock method for floor -1 is meaningless now, as that climbing mode has been replaced. This achievement is temporarily unobtainable and is expected to make a comeback in Version 3.0. I will remind everyone then on how to obtain it.

Which other obscure achievements have left a deep impression on you? Feel free to discuss in the comments!
