Herpling

Herplings are the weaker counterparts to the Derplings that spawn in hardmode Crimson environments. They act exactly the same as Derplings, although they do not jump as high. This is a dangerous enemy to early hardmode players, and is still an annoyance in mid-hardmode.

Trivia

 * This is probably a reference to the meme phrase "herp derp" along with the Derpling.
 * The name "Herpling" is likely a reference to the disease "Herpes simplex", aka "Herpes", whose blemishes and blisters match the form of the Herpling and the overall theme of tainted flesh in the Crimson.
