HELP THE KIND LION

In this STEM-centric series kickoff, young rescue workers shrink down to microscopic size to repair a lion’s leaky heart valve.

Aimed at fledgling readers, this first episode sends young Viv and Sanjay into an ailing lion’s circulatory system to discuss the heart’s general functions while taping up a torn cardiac valve. Despite its stilted dialogue—“The lion needs our help.” “We will help the lion!”—the tale has a lively cast. Along with enjoying the interior exploits of these fantastic voyagers, audiences will have effortlessly absorbed a modest but fundamentally sound quantity of anatomical information by the time the two are sneezed out in globs of lion slime to regain their normal sizes. Mahaney follows suit by kitting Viv and Sanjay out in cool techno-suits with octopuslike robotic arms, while tucking several extremely simplified diagrams of a four-chambered heart and its surrounds into the blocky, pastel-hued cartoon illustrations. Viv’s and Sanjay’s faces are drawn with lighter and darker shades of brown. Sound messages are imparted, though they’re a bit heavy-handed: The lion exhibits “kindness” by playing with lion cubs (and, to be sure, by not eating his rescuers); following an appended summary of heart facts, Ruths invites readers to create an "I am kind" badge and to also "make someone else's day a little better" by doing a kind act. (This review was updated for factual accuracy.)

Mostly purpose driven but with enough light touches to maintain the flow.
