We sincerely appreciate the feedback you have provided over this transition and can't wait for you to check out the new Xbox Forums!
Slimes do NOT spawn in on Peaceful. You have to be playing on Easy or above.
They spawn on the 4th block up from Bedrock, so your best chance is to dig down to Bedrock & then dig out like a 50x50 room & light it up so other Mobs don't spawn in. Make the ceiling like 5 blocks high. Or as high as you can. Also they don't spawn everywhere.
Only in certain areas, so finding them is a bit of luck.
