Beating Hush as T. Blue Baby hitless with no items.

That was much easier than I expected it to be, and I'd be damned if it wasn't for the creep. I noticed it disappears if I place too much of it, so I wasted some of it just in case. It may have something to do with entity limit.

Here's the overall strategy:
Normal - bare minimum amount of shield, sometimes used for damage
Corn - some fly damage, protected by the stone poop
Red - damage and used to ignite toxic clouds
Poison - most effective against flies and sometimes used for bigger explosions
Black - worse version of poison, quite useless actually
White - takes time and effort to be most effective, has to be connected to creep and at least one stone poop
Stone - used for solid protection and keeping the creep effects
Bomb - pretty much same as red poop, but more useful
Fart - knockback and poison at a very close range, usually used for clouds
Diarrhea - duite annoying way to deal some damage
Brown creep - main source of damage, hush has to stay at it at all times, sometimes used to deal lots of damage with white poop
