I've scoured the internet for any reference to this glitch and I've turned up empty-handed, so check it out. This glitch gives you a nice large chunk of Team Blast instantly. Kinda tricky to pull off, but I'd imagine it could shake up a speedrun or two. In fact, poor Egg Hawk gets the honor of showing just how easily you can break the bosses.
The thing is, I'm on the gloriously renowned PS2 version (don't even bother cursing me over it), and it's also an old-ish copy of the game; but I distinctly remember discovering this glitch about a year or so after I bought it. That said, anyone else with the game (PS2 or otherwise) is welcome to confirm this glitch. It's slightly finicky, but you should be able to trigger it eventually. I also don't know whether or not this glitch works when switching to Speed rather than Power.
Also: don't interpret this wrong, because to me this game is better than Adventure 1. Opinions, opinions.
