Derpling

Derpling spawns in the Jungle when Hardmode is activated. It seems to spawn during the daytime. This buglike monster jumps high and attempts to land on you. It can strafe to the sides in midair, making it a pain to deal with. One is advised to deal with them quickly, as they spawn fast and can easily overwhelm you.

They are immune to the Confused debuff.

Trivia

 * The Derpling has a Crimson counterpart, named the Herpling.
 * The Derpling and the Herpling are references to the meme "Herp Derp".

Bug

 * Sometimes the Derpling will jump through walls and still move like normal, except slower
