                    <description>&lt;p&gt;I have looked at any biome there is in the game and i never saw slimes spawning naturally.&lt;/p&gt;

&lt;p&gt;&lt;span class=&quot;image-wrap&quot; style=&quot;&quot;&gt;&lt;a id=&quot;119414_thumb&quot; href=&quot;https://bugs.mojang.com/secure/attachment/119414/119414_slime.jpg&quot; title=&quot;slime.jpg&quot; file-preview-type=&quot;image&quot; file-preview-id=&quot;119414&quot; file-preview-title=&quot;slime.jpg&quot;&gt;&lt;img src=&quot;https://bugs.mojang.com/secure/thumbnail/119414/_thumb_119414.png&quot; style=&quot;border: 0px solid black&quot; role=&quot;presentation&quot;/&gt;&lt;/a&gt;&lt;/span&gt;&lt;/p&gt;

&lt;p&gt;The slimes spawn here from the slime spawner when it is dark enough, so evidently it&apos;s a slime chunk*.  However, when you remove the slime spawner, no slimes will spawn naturally, regardless of light level, or moon phase.&lt;/p&gt;


&lt;p&gt;*I don&apos;t think it&apos;s a swamp biome as a) the water is not coloured when placed and b) I don&apos;t think the flat worlds have biome differentiation. &lt;/p&gt;</comment>
                            <comment id="312426" author="mega_spud" created="Fri, 10 Jun 2016 12:31:58 +0200"  >&lt;p&gt;&lt;a href=&quot;https://bugs.mojang.com/secure/ViewProfile.jspa?name=depressed-pho&quot; class=&quot;user-hover&quot; rel=&quot;depressed-pho&quot;&gt;depressed-pho&lt;/a&gt; There are definitely slime chunks in MCPE, slime farms set below level 40 work fairly well in the slime chunks.&lt;/p&gt;

&lt;p&gt;I think the issue is that in Flat worlds, the Slimes should be spawning much more readily than they do, as the whole world is set just a few blocks above bedrock.  Slimes should be spawning in the relevant chunks, and should be easily spotted as they aren&apos;t hidden in caves.&lt;/p&gt;

&lt;p&gt;One way to find slime chunks in a flat world is to exploit the bug &lt;a href=&quot;https://bugs.mojang.com/browse/MCPE-8560&quot; title=&quot;Slime spawners do not function outside areas that spawn slimes naturally&quot; class=&quot;issue-link&quot; data-issue-key=&quot;MCPE-8560&quot;&gt;&lt;del&gt;MCPE-8560&lt;/del&gt;&lt;/a&gt;:  By placing lots of slime spawners across a large area spanning several chunks, the slimes should only spawn in the slime chunks.  Once the slime chunks have been discovered, they should spawn there without a slime spawner in place.  (Hope that makes sense!)&lt;/p&gt;

Unlike the PC version, MCPE doesn&apos;t have the concept of slime chunks. It&apos;s an intentional difference.&lt;/p&gt;</comment>

                            <comment id="256647" author="plethora777" created="Tue, 20 Oct 2015 15:59:30 +0200"  >&lt;p&gt;&quot;Slimes only spawn in slime chunks under Y 40&quot; &lt;/p&gt;

&lt;p&gt;We don&apos;;t have access to coordinates so how would we know which chunks are slime chunks + what is under Y:40.... (okay that was a bit smart a**)&lt;/p&gt;

&lt;p&gt;I have used an online tool to discover which chunks should be slime chunks (if MCPE uses the same algo as MCPC) and I have made spawnable areas in these chunks below Y=40 and I have not seen any slimes.  I have hollowed out 5x5 chunks (that is 5*16 x 5*16) with the idea that MCPE might use a slightly diff algo.  Still no slimes.&lt;/p&gt;

&lt;p&gt;Furthermore I&apos;ve played a LOT of MCPE.  I have never ever, not even once in all that time seen a single slime in survival mode.  Nada.  &lt;/p&gt;

&lt;p&gt;It seems very very unlikely to me that slime spawning is working as intended.&lt;/p&gt;</comment>
