This contains my current times. If you have a worse time that is still Platinum I can add it as well to make the cutoff clearer.

Any assist mode other than pull rope (which is required) will nullify your time and badge so you have to do these 'legit'.

NOTE: I did all of these by myself controlling both characters so it is possible if you don't have someone to play with.
