This is exactly what it claims to be: a sweet, silly, safe graphic novel series for early readers. The friendship between perpetually cheerful Narwhal and more reserved Jelly is genuinely endearing, and the underwater absurdism (waffles! unicorn horns! parties!) hits the sweet spot for the 5-7 crowd.

The books won't change your kid's life or teach them calculus, but they'll build reading confidence and model healthy friendship dynamics without being preachy. Common Sense Media and parent reviewers consistently praise these as home runs for the target age—and that 4.9 Amazon rating backs it up.

The main caveat: there's not much plot. These are character-driven vignettes about friendship and imagination, so kids who need action and stakes might get bored. But for the right reader at the right moment—that kid who just learned to read and needs something fun and achievable—this series is gold.
