i documented all the uka uka trials so you know what they're about without playing them because you're a lazy bastard
trial I - unlocked in memory lane. this trial is about double jumping through various pits while hitting time stoppers.
trial II - unlocked in snow way back. this trial is about carefully avoiding nitro crates.
trial III - unlocked in stream lining. this trial is about finding the nitro switch crate within to unlock the exit.
trial IV - unlocked in silver lining. this trial is about carefully jumping through the massive gate of crates to get the uka uka and double jump to the exit. you can't break too many crates on the way in or you'll have none on the way out. break all the aku aku crates to get rid of the nitro and so that they don't get rid of your uka uka.
trial V - unlocked in castle mania. not much here. doesn't even need uka uka to be beaten.
yes i know these trials from experience, here's proof of my experience
