Not a very long DLC. It's basically just a roguelike, where you defeat scenarios and get more characters, Sparks, etc. for your arsenal. Ended with Rabbid Rosalina, Rabbid Peach, and Rabbid Mario. The reward for beating it the first time is... a weapon skin. Not very much to it. Once you finish the "story" once, you unlock a premium mode, which gets harder and harder as you go on. Not going for the 100%. Excited to try out "The Last Spark Hunter" in the future.
