Poison Mushroom

A Poison Mushroom is an exclusive Item for two select racers in Super Mario Kart- Princess and Toad. However, it is only available for CPU controlled characters; otherwise, you get the regular Question Blocks.

Poison Mushrooms are thrown out right in front of your kart. However, Princess and Toad can also drag them behind their karts, so don't hit them from behind.

If you hit a Poison Mushroom, you get shrunken down to a very small size, similar to the Lightning Bolt, which causes you to lose speed. Another kart can then proceed to drive over you to flatten you, causing you to lose even more time. This danger makes it very important to get an antidote. The first is to sacrifice your self and get crushed, but a more reasonable way is to hit another Poison Mushroom... it returns you to normal somehow. And yes, they can also return you to normal size after a Lightning strike.
