Scooby-Doo Team-Up #21

In "Happy Harley-Daze!", Harley Quinn tries to prove she’s a true detective by teaming up with Mystery Inc. to unmask a Christmas ghost—only to find the case takes a wild turn when the Joker crashes the sleigh with a scheme of his own. Written by Sholly Fisch and brought to life by Dario Brizuela’s dynamic art, this festive mystery blends holiday cheer with classic Scooby-Doo antics, all wrapped in a cover by Brizuela that captures the chaos in bold, playful detail.
