No. Because your world is different from everybody else's and therefore the website would not be able to find slimes in all of those worlds.
You can find slimes in flat areas at lease 6-7 blocks wide. Or in slime dungeons.
Not in the current version, at least not often.
There are 3 sizes of slimes in Minecraft that naturally spawn. Big, Small, and Tiny.
The flat world seed spawns alot of slimes. But every seed spawn slimes.
In the bottom layers of the map or (if you have Weekly Snapshot 12w40a or above) in swamps.
Apparently yes. But the smallest slimes don't harm you, they don't deal damage.
Peaceful mode means that no monsters spawn, so there will be no Slimes.
No, not as of March 27th, 2013.
Slimes can, and awkwardly creepers can too.
Slimes cannot spawn in the Nether in Minecraft. They are exclusive to the Overworld, where they spawn in specific biomes and under certain conditions, primarily in loaded chunks below Y-level 40. In the Nether, you would typically find different mobs and creatures, but slimes are not among them.
step 1 find slimes underground (hint: look DEEP underground) Step 2 make the area where you found slimes easly accseable step 3 kill all the slimes step 4 leave and then later come back to kill more slimes step 5 ?????? step 6 profit
Yes, Slimes are hostile and will attack players on difficulties other than Peaceful (they won't appear at all in that), or Creative Mode.
