1) These bottles are extremely flammable...

...if one catches on fire it will keep burning until someone picks it up, anyone who does runs the risk of catching on fire themself.
2) Found another use for the Jello...

...as a projectile, whoever you throw it at if it hits them (like that Titan) it bounces them really high in the air. Unlike the Titan, most standard players will go SPLAT when they hit the gorund.
3) More brocconade issues...

...it turns out that after you've had one and thrown it, you can't go back to where you got it to pick up a new one. It won't let you pick up a new one until after you've gotten killed. How messed up is that?!?
