Yep, knew both of those things.
Brawl has a bunch of wierder, situational quirks:
-ZSS does a horizontal air-roll thing if she tries to up+B into a flipstool while right on top of someone who is standing on the stage
-Jigglypuff will vertical-KO herself if her shield breaks
-Marth can trap someone with his down tilt by using it over and over again to pin him/her against the rightmost pillar in Hyrule
-Pikachu will jump on the second quick-attack if you Quick-attack to the ground and then try to QA off of it.
-Pit and Jigglypuff can be in Neutral B forever.
-Sonic's down Smash can spike. The hit box is directly under him (literally on the stage), however, so it's only doable on stages like Delfino Plaza.
etc. etc. etc...
