Poison joke

Poison joke, seen in the episode Bridle Gossip, is a magical plant that causes ridicule-inducing afflictions on ponies who come into contact with it.

In the episode, the ponies accidentally stumble into a large patch of poison joke despite warnings from Zecora. The plant appears to have large leaves, with a multi-petalled bulb sticking out of the center, each bulb sporting a few stamen. The entire plant is blue, including leaves and stalk, with dark streaks running over it in a design.

Like its namesake, poison oak, it appears to affect anyone who merely comes into contact with it, but as described by Zecora, the plant does not poison, rather it plays pratical jokes, which manifest as physical afflictions. The jokes seems to be able to magically match the victim's personality and traits.

In the episode, the six main ponies undergo the following pranks:


 * Twilight Sparkle's horn turned limp and spotty.
 * Rainbow Dash's wings moved from her back to her stomach and she keeps crashing when she flies.
 * Applejack shrank down to the size of an actual My Little Pony doll.
 * Rarity's hair grew uncontrollably and turned into a mop.
 * Pinkie Pie's tongue became swelled up, disabling her speech.
 * Fluttershy's voice turned into that of a soulful old man's with an African-American accent, but she does not want to talk about it.

The effects of poison joke can easily be countered by taking a herbal bath; the recipe of which can be found in a book called Supernaturals: Natural Remedies and Cure-Alls that are Simply Super.

Trivia

 * As it's never shown in written form, it's possible that the name is spelled "poison joak" after its namesake poison oak.
