The Grumpy Darkling was never implemented, but it is seen several times by players. In the starting video, they are been ravaging the town, and are seen in many other places. Originally, it was going to be an enemy, along with Hyper Darkling and Freak Darking, but they were all removed before Alpha was started. However, the Hyper Darkling can still be seen in-game today through Portabello. The Grumpy Darkling's attack is a swing of its' hammer, which can be seen in a video titled, "Darkling Battle".
