Apparently there are quite a few other ways of getting Diddy frozen, too; you can watch blademiester's other videos to see more ways of doing this.

Ah, so it's not nearly as severe as the Melee freeze glitch because you get unfrozen if you get hit or are pulled off the stage.

Diddy players got to watch when they uthrow. Although, is uthrow even a good throw for diddy?

I'm not sure if uthrow is good. None of the good Diddy mains I've played used it all, but I've only played a couple of them.
