Why Some Things Are Rare

You may have noticed: some things your turtle brings home easily — like ordinary shells. And some things seem to never appear, like those glowing deep-sea fish.

Here’s why.

That’s just how the ocean works

Imagine you’re at the beach. You bend down and pick something up from the sand — most of the time, it’s a plain shell. They’re everywhere. Occasionally you find a pretty spiral one, but that takes luck. Finding a live octopus just lying there in the shallows is almost impossible — they live in the deep.

The world we designed for your turtle works the same way:

  • Common things: You’ll find them almost every time. That’s not unfair — they’re just abundant in the sea.
  • Somewhat rare things: You might find one every few trips. Like a piece of beautiful coral.
  • Rare things: Takes many trips before one appears. Like a tiny glowing jellyfish.
  • Very rare things: Takes a lot of trips, and some luck. Like things you’ve never seen before.

We don’t have a “cheat mode”

Some games let you guarantee a rare item in certain ways:

  • Log in 7 days in a row to earn a rare
  • Invite a friend and get a rare
  • Watch an ad for a rare
  • Buy a rare

We have none of these.

Why? Because if something rare can be “farmed,” it stops being rare — it becomes a grind target, not a genuine surprise.

Also, we don’t want you to keep staring at Tortoise Time just to chase a rare item — that would just be another way screens pull you in, which is the opposite of what we’re going for.

So how rare is “rare”?

We’re not going to tell you the exact numbers.

If we said “this item appears 0.5% of the time, that one 5%,” you’d start calculating “how many trips to collect all the rare ones.” That turns it into a math problem, not an adventure.

Let your turtle bring back what it brings. Don’t expect a particular outcome.

  • Got a plain shell? That’s wonderful — it’s called “common” not because it’s ugly, but because it’s free and plentiful in the sea.
  • Got something rare? Exciting! Flip to the journal and see what it wrote.
  • Still no rare after many trips? That’s fine. Time is long. Somewhere out in a nighttime ocean, it’s waiting for your turtle to find it.

Some advice for you

Don’t tell yourself “I need to get something rare this time” — the more you think it, the less it seems to happen. Don’t dispatch over and over trying to force a specific item — your turtle doesn’t know what you want. It just brings back what the ocean actually has.

Slow down, let things come to you. That’s when this game is most fun.
