"This old Cavern Crasher wanders out during Eternal Night, unintentionally wreaking havoc all over Berk."
Slimeslinger looks similar to a normal Cavern Crasher. However, he has bright orange "mucus-producing bubbles" on his back, compared to the normal black off a Cavern Crasher. He is reddish brown in color with some orange on his face, legs, and underbelly. He has bright orange eyes.
