can I get some help with a slime sub race? I was thinking a bonus to constitution and dexterity. For Unarmored strikes maybe a range of ten feet not 5(they extended their limbs)? Because they are only half slime, they will still have bones. Other than that I have no ideas, help!

Plenty of oozes have the Amorphous ability:

Amorphous. The ___ can move through a space as narrow as 1 inch wide without squeezing.

You could this as an ability that you can use for 1 minute per long rest. AFAIK every ooze has blindsight and many have resistance to acid damage.

Blindsight is VERY powerful.  Negates a whole school of magic plus other things.   Diviners get it at 10th level for only 10ft.  

I would consider something along the lines of this:

Con +2 and no other stat bonus.

Darkvision 60 ft.

Speed: 30 ft,  Swim speed: 30 ft, Climb 20 ft

Squeezing Speed 30:   While squeezing through a space, you move at 30 ft,  do not receive disadvantage because you squeeze,  nor do others have advantage for attacking you.

Pick one Resistance.  You can not change this one chosen:  Acid, cold, fire, lightning, poison, non-magical/non-silver slashing, non-magical/non silver piercing damage.

Sure. I meant to say that you get blindsight when you enter your ooze form, lasting for a minute per LR.
