# Dens

What are Dens?
Dens are special, timed encounters that spawn randomly.
They appear as a **sparkling area** in the realms. They are **player-specific**, **meaning that only you can enter and clear your own den.**
Inside, you’ll face off against a **random boss** Pokémon for a chance at special rewards.

{% hint style="danger" %}
Dens that appear in the **Safari Zone** or **Raid** server cannot be entered.

How Dens Work
When a den spawns, you will receive a notification. Keep a close eye on sparkling areas!
\
To enter a den, right-click the sparkles to begin the encounter.
{% hint style="info" %}
**Tip:** If you are having trouble locating a den, enable hitboxes by pressing **F3 + B**.
{% endhint %}
***
Defeating the Boss
Dens have a time limit. Locate and defeat the boss within 10 minutes of entering. Sometimes the boss is obvious, other times it’s hiding in a group of Pokémon! A den is cleared once the boss Pokémon is defeated.
**Victory can achieved by:**
* Catching the Pokémon
* Fainting it in battle
Once the boss is defeated or if you fail to beat the den, you will be returned to the surface in 15 seconds.
{% hint style="warning" %}
If you need to leave a den for any reason and do not need to return, use **/leaveden**.
{% endhint %}
***
Rewards
Clearing a den can grant a variety of rewards. These range from simple consumables to more valuable items, such as crate keys, raid passes, or shiny vouchers. Rewards are random, with different bundles available as possible outcomes.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.
Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:
```
GET https://wiki.cobblemonislands.com/features/dens.md?ask=&goal=
```
`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.
Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
