If that gelatinous cube has carrots, marshmallows, pineapple and walnuts it will definitely win.

I’m not sure a mimic can grapple with a gelatinous cube, but the cube can definitely engulf the mimic. If the cube catches and engulfs the mimic that’s pretty much it. 21 + (6d6) vs (1d8) ? a turn isn’t even a long wait.
@Nate311. Mimic would mimic either the gelatinous cube or … what does gelatin fear the most ? Hot water!
@MarkDaSpark That’s not what a mimic does.
@Nate311 The gelatinous cube would absorb and eventually digest the mimic.
I don’t know that the gelatinous cube has enough intelligence to be fooled by the mimic mimicking. Which would mean it’d win, I think.
Pretty much to win against a cube you need a ranged weapon
