Less blinding, more slippery, I'd think.

It depends on how the rules explain it. ATB/Road Hogs explicitly had their Octopus ink cloud work in air or water.
As for explanation, what you would want to do is aerosolize the ink to where the droplets are fine enough to float. Which would look nothing like Hachi's Fire Hose.
And for the record: Animal summoning, special attack, multi-armed swordsman, spikey hair, and he's an idiot? Anime Hachi should have his own series.

Hell, you could incorporate how he--like pretty much every other low-level One Piece character who got wrecked by the Straw Hats--ends up working at a restaurant. Badass swordfighting over the best ingredients, shonen challenges over who makes the best seafood, and so on...

And delicious served over pasta.

I said the same thing about the scotsman in Samurai Jack. It would be called "Me own bonnie show!"

You should pitch this idea to Cartoon Network.

Stinking cloud. Smoke Cloud. Death Cloud.

There are many clouds in Tabletops, and all of them are potentially NASTY. Share a story about a particular Cloud from your games, for good or really nasty ill.

So, in our currently still (barely) ongoing Rise of the Runelords campaign, we met a buinch of water demons who could all use Obscuring Mist (IIRC) at will.

With two ranged attackers in our group this was quite the issue of us in theory. There was only two flaws with their plan.

1) They couldn't see through the mist themselves.
2) My character (the Sylph, meaning part air-elemental) could see 15ft through any magical fog or similar. And the blind oracle didn't really care about sight at all, relying instead on blindsight/sense.

Which meant they hampered themselves more than us really. And when they started doing hit-and run attacks, using a swift action teleport-in-water combined with moving in and making a single attack. All it took for us to get the upper hand was use readied actions to strike when they did.

All in all it was kind of funny how that fight went, if really tedious.

I nearly caused a TPK with Fog Cloud.

Dark Sun setting, Water cleric. Buncha rebel types getting ready to assault a caravan. I decided to embellish on the plan by obscuring the section of the battlefield we were using to approach in a Fog Cloud, and between the confusion it caused our undisciplined allies and the terror it caused our *superstitious* allies, a bunch of them broke and started to run. We got away, too, but it was a near thing and I lost my Fog Cloud privileges for a while.

We all love Potions of Obscuring Must, right? Make for a great ninja escape trick.

Except when you use it in a long, straight, narrow hallway and there are enough crossbow bolts flying your way that it doesn't matter they can't see you, you've still got a 90% chance of getting pincushioned.

Our alchemist hasn't let my Rogue have any since.

The best one is the cotton candy cloud of Discord

In one arc, I had a villain who carried an incendiary cloud item and a poison cloud item, which were set up to a heart rate monitor he wore. If he died, they both went off. He got knocked out. Party found the heart rate monitor and the cloud items.

The lawful good party healer then decided to kill him, filling the entire building with toxic, burning gas.

To this day, the party seems not to realize that was either completely out of alignment (killing an unconscious enemy for revenge's sake as an LG character) or a terrible tactical decision.

I fail to see how either of those are exclusive preventing it from being both.

Both are the case, and the party hasn't realized either.

Funny you should mention stinky clouds, as the ink of cephalopods ALSO impairs their persuers sense of smell.

playing a mashup game for fun, made a spell that let me use a magic charm to summon .. a cartoon type idiot.
(think of Ed from the Edds show, only wackier)

spell worked great, the idot 'bubba' had damage resist like crazy so we kinda used him a distraction/ shield.

the downside... I didn't know how to cancel the summon so we would up STUCK with bubba and two others I summoned by mistake trying to send him back.

woulnt have been as bad cept both the ranger and one of my summons was a NUT.

took a nap to regain energy and found they glued my feet to the wall.

and my left hand to my butt.
