BoB Simultaneous Cutscene Glitches

I show 3 different glitches that result from activating 2 cutscenes at once in BoB. In order, these are:
(1) Releasing Chain Chomp + Defeating King Bob-omb 0:00
(2) Releasing Chain Chomp + Racing Koopa the Quick 3:51
(3) Entering a Cannon + Opening a Star Box 6:24

I've shown (2) before, but now show it again in more depth. Interestingly, (2) can transition into (1) by using a teleport or activating a star. The running theme of these glitches is weird camera angles and softlocks. By the way, anytime the camera is fixed on chain chomp, it's difficult and unintuitive to control Mario's direction. I don't know if these glitches have any practical application, but I made sure to test every possible situation I could think of in this video for the sake of documentation.
