Toadstool's name is a little self explanatory. With the ability to produce mushrooms anywhere and will often use this power to suck her enemy's life. However it does come with some drawbacks. Toadstool has chronic pain and her pain medication was no longer working so she started smoking natural pain killers, like the mushrooms she produces. On a plus side it's not she can get high off her own mushrooms.

Whinifreds brother Poisondart as a teenager discovering that he can grow facial hair for the first time.
His dad went missing before he and his siblings were born (he's a decuplet but him and Whinifred are considered twins). And him and his brothers never had a dad to teach them about being a guy. So he had no clue about certain things including facial hair.
Poisondart never really had friends growing up, he mostly hung out with his siblings, so he was left in the dark about all of his body changes, and since his brothers were in the same boat they were no help. He eventually just went to the library to findlb answers. But books can't replace your dad and he knew this, but felt like he had no other options.
