Hmm, in fact I never noticed this "trick".
I always get bumped, and miss the entire dash xD
One thing I noticed is that lickers bump you more, but this everyone knows I guess.
Another thing, is that sometimes in PA at the beginning, I have a bug, I dash and pass through them, however I don't do any damage to them. It's happened 3 times with me, and is really weird.
Yes that happens to me from time to time but nobody believes me when I say it xD it happens like 1 in a 100 times.
Same here xD
and when this happens, you don't even hear the sound of the "impact" with the majinis, when dashing.
Literally sliding through them, without doing any damage.
