Mutant Ninja Mouse

A few of Furoma's finest ninja mice seem to have been also caught off guard while training nearby. While being agile enough to avoid most of the toxins and spillage, the small amount they were exposed to looks to have increased their body mass and speed while also providing excellent nightvision!

The piles of old clothing scraps near the spill location ended up absorbing the sludge, turning them green, which they quickly adopted as their new uniform. With the added strength and agility, they are also able to keep multiple weapons handy on them at all times, such as chainsticks, long staffs, prong-shaped metal batons, and short swords.

Even after discovering the secret of the ooze and gaining new powers, they are still humble warriors who never forget the wise words of their master: "Remember who you are."
