Frozen in Time (Pablo and Splash #2)

Dempsey spins an energetic time-travel yarn in this graphic novel sequel. Penguin chums Pablo and Splash think they’re going on a simple vacation to visit their human friend Professor O’Brain, initially portrayed with pink hair and pale skin. But when they arrive—via a topsy-turvy tunnel from their polar dwelling to the professor’s lab—and find that O’Brain has vanished, cautious Pablo’s desire for a relaxing retreat dissolves (adventurous Splash, meanwhile, is excited for the excursion). They soon learn that Professor O’Brain’s sentient—and snarky—invention, TimeBender, has abandoned its creator 68,000 years in the past, in “Ice Age. Northern Europe.” And if the penguin duo wants to rescue her, they must leave her cozy, snack-filled abode for unfamiliar, bison-populated terrain. Time-travel shenanigans add an unexpected bent to Splash’s devil-may-care nature and Pablo’s more sensible demeanor, which evoke Odd Couple dynamics familiar to the genre. Bouncy and brightly colored illustrations are accompanied by scientific facts surrounding the climate and animal extinction throughout. It’s a simultaneously chuckle-inducing and touching series addition that teaches about the value of home and friendship and encourages readers to be curious and seek adventure. Ages 7–10.
