The Super Sidekicks return to save humanity from a dangerous foe-who turns out to be of humankind's own making.Following their origin story in No Adults Allowed (2020) and still trying to establish themselves as legitimate crime fighters in their own rights, the Super Sidekicks become aware of a new threat to Sydney. An enormous monster made of bits and pieces from the Great Pacific Garbage Patch has invaded the harbor, and the adult superheroes have mysteriously disappeared. Junior Justice, Flygirl, Dinomite, and Goo use their individual talents and teamwork to take down the power behind the monster-who is ultimately trying to protect the ocean and its inhabitants. While the heroes' solutions to plastic pollution are oversimplified and unrealistic, the message promoting urgent environmental action is presented in an accessible and entertaining way. Importantly, this second volume maintains the goofy humor and dynamic action scenes that made the first book so enjoyable. Dinomite's sarcasm is acerbic without being abrasive, and Junior Justice prompts lighthearted laughs by taking himself just a tad too seriously. Highly effective and engaging layouts help readers follow the action, and shifts in perspective and panel size immerse readers in the lively, energetic scenes. The bright, cartoony colors reinforce the heroes' sunny outlook and exuberant tone. Junior Justice is cued as Southeast Asian with black hair and light-brown skin, and Flygirl reads White, with pale skin and red hair. The adults are a mix of racial presentations.Fun with a socially conscious message-these heroes charm with humor, talent, and, above all, friendship.
