Herplings are 敌怪 that spawn in the 猩红 during 困难模式. They attack the player by quickly jumping across the ground. While they can't jump very high, they can cover horizontal distance incredibly quickly, making them a potent threat.
- They behave the same way as 史莱姆s do in water.
- Herplings can be difficult enemies due to their speed and knockback resistance.
- The 跳跳兽 is often considered to be a counterpart to the Herpling, as both have names based on the phrase "herp derp".
