My kids have been obsessed with ocean facts lately, and this octopus does not disappoint—we counted all eight arms and then looked up the three hearts thing online. It's a fun little model that makes learning feel like play.

The blue blood detail is fascinating and a great conversation starter with my kids. I wish the description included more about their natural habitat to spark deeper learning.

I was surprised by how much personality these creatures have—the way they use their eight arms to explore everything is fascinating. The ink-squirting behavior is a hit during our aquarium visits, though I wish the guide had covered more about their three hearts.
