When I first saw the show I thought it was just some kid show that isnt that good but when my brother showed me a episode it was really cool! Im 12 and I like it! My fav one is peso because he is really cute. I aslo like shellinton or whatever. It also can teach you about ocean life and things it's like wild krats but underwater, more story like, and BETTER. I also watched the one on netflix the caves of sac actum. I dont know spanish but if you have netflix you should watch it its good.🦈🐬🐙

my 2.5 year old looooooooooooves this show. he is obsessed with Sea Creatures, and this show does an amazing job of introducing TONS of Animals! He points them out in books and at the aquarium, it's wonderful. We live in Finland, so Netflix is not an option (only s.1&inFinnish) and Neither are the majority of streaming services. As it is, I don't mind paying for the programs that are a positive influence for my kid. Please ADD more Seasons of the show soon! I will buy those too! (HD could be cheaper

This show is great. The animation is adorable and my son learns a great deal about different animals in and around the ocean as well as the various niches in the environment. Others shows can get annoying with the songs and trademark tag lines, but Octonauts never gets old. If you have Netflix or On Demand, don't waste your money on this, you can find episodes on there. My son absolutely loves Kawazii and runs around saying "Yeow"...hope someone makes Octonauts costumes next Halloween.
