Super Stink Cloud is no longer an alternate ability. Instead, it is now the default Stink Cloud, replacing the Zombie Stink Cloud. It now takes 30 seconds to recharge and lasts for 15 seconds.
Origins
It is based on a smoke grenade, a canister-type grenade used as a signaling device, a target or landing zone marking device, or as a screening device for unit movements.
Strategies
With
Preferably, try to throw it in a huge area of plants. This is very useful in the Gardens & Graveyards mode around the garden to cover up your teammates and deal damage to the plants at the same time. However, it will not last for long and has a smaller radius. Act quickly and capitalize on the plants as soon as you throw it. In addition, try and have an Engineer around if you use this for cover, as there may be a Chomper ready to kill you hiding in the cloud. As a last ditch method, if you are going to die, and you know your opponent is as well, throw this at your opponent and hope it vanquishes them.
Against
When you see one flying, run before it hits the ground. But remember, Chompers can burrow through the cloud and not receive damage. They can also hide in the cloud and strike zombies that are hiding in the cloud for cover. However, doing this if zombies behind it are in crowds will likely get yourself killed. Another strategy is to use Spikeweed where it landed, as some zombies may try and hide in the cloud.
You can identify Super Stink Clouds from regular Zombie Stink Clouds by looking at the cloud. If there are skull patterns, it's a Super Stink Cloud. Prioritize not going to those areas unless you're sure you can survive.

Trivia
If the player was vanquished by it, the game will still say that they got vanquished by the Zombie Stink Cloud in both the "Vanquished By" section of the kill cam and vanquish feeds.
According to the sticker, the canister has the same face drawn on the Multi-Rockets.
This and the Zombie Stink Cloud will burst on the first thing it touches, similar to the Long Bomb.
If one listens closely whilst near the Super Stink Cloud, they could hear small fart sounds, suggesting that it is very stinky and damaging.
