Worst/Hardest prankster comet missions

[Fazer]

I had a ton of trouble with the Speedy Comet mission in Boss Blitz Galaxy. It's just that I lose way too much time chasing that bastard Fiery Dino Piranha.

This and the Ghostly Galaxy purple coin mission.

There's a difference between something that is challenging and something that is hard.

No! No different! Only different in your mind.

Go play Ikaruga, and you will know the definition of "challenging".

Play something like... Superman 64, and 100% it. That's hard.

but that's not even hard/challenging

it's just dumb

It's hard in a dumb way.

How about Gold Star every level in Kirby Mass Attack?
