Both Toxtricity forms have had a few plush released so far. The Amped form seems to be the more popular one as of right now, having three plush released as opposed to Low Key's two.

Amped Toxtricity Pokémon Center Plush

Manufacturer: Pokémon Center (Japan)

Product Line: Pokécen Plush

Release Date: August 27 2020

Purchased From: N/A

This was the first Toxtricity item I ever owned, and was given to me for Christmas one year. He's missing his tag, but it's not really a big deal since I still have it and can reattach it if I ever feel like it.

Low Key Toxtricity Pokémon Center Plush

Manufacturer: Pokémon Center (Japan)

Product Line: Pokécen Plush

Release Date: August 27 2020

Purchased From: Discord

Like his brother, he has a hard "skeleton" that lets you pose him however you want. I wish his mohawks would stand up a little better, but I guess it doesn't matter too much.

Amped Toxtricity All Stars Plush

Manufacturer: San-ei (Japan)

Product Line: Pocket Monsters All Star Collection

Release Date: September 5 2020

Purchased From: Mercari Japan

I think I like these plush better than their Pokécen counterparts. The fact that the mohawks are sewn rather than just a flat piece of fabric makes them feel a lot higher quality, in my opinion.

Low Key Toxtricity All Stars Plush

Manufacturer: San-ei (Japan)

Product Line: Pocket Monsters All Star Collection

Release Date: April 2021

Purchased From: Mercari Japan

This guy was released a bit later than his Amped brother. I had a pretty hard time finding one for a not ridiculous price, but thankfully he's here now.

Amped Toxtricity Pokémon Posing Plush

Manufacturer: Pokémon Center (Japan)

Product Line: Pokémon Posing

Release Date: March 18 2021

Purchased From: eBay

The name "Pokémon Posing" feels a bit redundant here since most other Toxtricity plush are already poseable, but I guess that doesn't apply to the other Pokémon featured in this line. He's way tiner than I thought he would be, which I feel makes him pretty cute.
