“Oh, Crash. The farmer's market is tomorrow and my wumpa trees won't grow for my orchard is riddled with greedy worms. If you rid my land of these pests, I'll give you this Power Crystal.”
—Farmer Ernest, Crash Twinsanity
Ernest's only appearance was on Crash Twinsanity, in which he asks Crash to get rid of a swarm of worms in his orchard. The player must use Cortex as an hammer to smash the worms in the time limit and let the Wumpa trees grow.
The farmer promises Crash a power crystal if he accomplishes the deed, however, he is immediately paralyzed by Doctor Neo Cortex, who takes the power crystal anyway.
There is concept art of Farmer Ernest holding a pig in the enemy gallery. Though he is not an enemy in the game, he is one of the many characters that, for some reason, hurt Crash when the player uses a glitch to touch them.
Farmer Ernest's appearance in the game is a parody of the video game trope of a side characters asking the hero to do a favor for them in exchange for a reward (A seen in video games like "Spyro the Dragon" and "Jak & Daxter")
