Fun Guy But Bitter is an achievement that requires the player to harvest bittercap mushrooms in the farming patch west of Canifis which requires a bittercap mushroom spore.

This can take up to 240 minutes (4 hours) to grow. Players may use boosts to complete this achievement, such as pork pie at Farming level 48, but they must be redone before harvesting to complete the achievement.


  • This achievement used to be a task prior to the release of the Achievements System on 18 April 2017.
