Blogg Morph Ball Glitch
From M2K2: Metroid Prime 2 Wiki
If you shoot a missile at a Blogg, then turn into Morph Ball mode, the Blogg will grab you and you will lose a bunch of health. This is not unusual. However, if you freak out and drop a Power Bomb in its mouth, It will be destroyed, drop you and you will look just fine. You can drop bombs, PBs, and boost. But you may notice YOU CAN'T UNMORPH. You will have to reset the game. My guess is this is because the game thinks you're still in its mouth and therefore disallows unmorphs.
