The Leprechaun Flu is a disease that only leprechauns can presumably get. Liam the Leprechaun caught the flu in the episode with the same name.

Stage 1: Burping out Bunnies
The leprechaun starts burping out bunnies. Grapefruit thought this was stage 4 of the Flu.

Stage 2: Sneezing Rainbows
The leprechaun sneezes rainbows. Liam states that after a sneeze that the leprechaun "feels so incredible, they have to ponder".

Stage 3: Farting Gold Coins
The leprechaun farts gold coins. Midget Apple thought they smelt bad but Liam said they "smell like fresh clover after the rain" and it was "mighty inconvenient when you're farting all the time on the job." But Little Apple tells Liam he's rich, thinking it's a good thing.

Stage 4: Spontaneous Combustion
This is the final stage of the Leprechaun Flu. The leprechaun explodes. According to Liam, the leprechaun uncontrollably adds syllables to words as a sign of reaching stage 4.

Cure
The cure for the Leprechaun Flu is for any orange in the vicinity to stop talking. Orange says he can't do it, but Liam was being sarcastic. But Liam exploded before he could explain the actual cure. The actual cure is currently unknown.
