Sea creatures capture the imagination early. Long before a child can read the word “octopus,” they can recognize one, imitate one, and — if the tune is right — sing about one. That is the territory The Learning Castle works in: a YouTube channel that has been turning facts about animals, insects and sea marine creatures into rhymes and melodies since it joined the platform in September 2021.
The channel now lists more than seventy public uploads, and a good share of them look straight at the ocean. Alongside The Whales’ Love Song! and Sharks!, viewers will find Octopus! — Fact-Teaching Song and Starfish Story Song!, plus a longer Dolphin Episode and a handful of stranger sea characters. What follows is a closer look at why sea life suits songwriting so well, how four very different creatures are handled musically, and how the songs can be put to use at home, in a classroom or in the community.
Why Sea Creatures Make Such Singable Subject Matter
According to the channel’s own description, the method is refreshingly simple: the creator takes cool facts — mostly about animals, insects and sea marine creatures — rhymes them, and sets them to music. That one sentence explains a great deal about these sea-life songs. The rhyme is not decoration. It is the delivery system, a way of turning a curious detail about an ocean animal into something a listener can repeat, remember and sing back without ever feeling quizzed.
The stated goal is just as clear. The channel sets out to provide quality songs that both children and adults can enjoy, and the description openly acknowledges a familiar complaint: many adults find kids’ songs annoying. The hope expressed there is that this style appeals to “kids” of all ages, and that children all over the world will be singing these songs and learning interesting facts along the way. That ambition — a sing-along that does not wear out the grown-ups in the room — quietly shapes everything from subject choice to tone.
Each song and each full episode is also paired with a free accompanying lesson at Teachers Pay Teachers under The Learning Castle, as the channel states. For a sea-life song, that pairing matters. The music introduces and reinforces; the lesson gives the same material a second, quieter shape for later in the day or later in the week.
The audience the channel names is broad: ESL learners, preschoolers, students with ADHD, late-start readers, homeschoolers, and families looking for sing-along entertainment. Sea life fits that range unusually well. A whale, a shark, an octopus and a starfish are recognizable to a very young child and still interesting to an older reader, which means a single song can sit comfortably in a preschool circle, an ESL classroom and a family car ride without being pitched out of any of them.
Whales, Sharks, Octopuses and Starfish: Four Musical Angles
What makes the channel’s ocean catalogue interesting is that no two creatures are treated the same way. The titles alone reveal a range of approaches, from jazzy love song to fact-teaching song to story song.
Whales
Whales appear more than once, and the channel leans into romance. The Whales’ Love Song! and Whales! – Jazzy Love Song both frame whales through affection and jazz rather than through a dry checklist of characteristics. That is a clever choice for mixed audiences, because a love song is a familiar form and a jazzy arrangement is pleasant to have playing in the background. For children, the framing gives the animal a personality to latch onto. Ocean mammals also feature in the longer Dolphin Episode, suggesting that this corner of the catalogue carries fuller lesson-style videos as well as short songs.
Sharks
Sharks! takes a bolder route. The shark tends to arrive in a classroom with a reputation already attached, and a song is a useful way to meet that reputation head-on. The single-word title, punctuated with an exclamation mark, signals energy rather than solemnity. It is consistent with the channel’s broader habit of giving big, attention-grabbing creatures their own musical moment — alligators, spiders, vampire bats and roaches all get the same treatment — rather than steering away from the animals children are most curious about.
Octopuses
The octopus song is the most explicit about its purpose: Octopus! — Fact-Teaching Song announces in its own title that facts are the point. Rhyme is the mechanism, but the label makes a promise about information. The cephalopod theme reaches further too, with THE MYSTERY SQUID SONG! as a companion piece for listeners who like their sea life a little stranger, while PSYCHEDELIC FROG FISH! and RIDING ON A LOBSTER TAIL! add even odder ocean characters to the line-up.
Starfish
Starfish Story Song! takes a narrative approach. Where the whale songs promise romance and the octopus song promises facts, the starfish song promises a story — a structure children already understand from picture books. Story gives a song a shape beyond verse and chorus, and it gives a listener a reason to come back and hear how the whole thing unfolds.
Read together, these four titles suggest a consistent philosophy: pick a creature children are already curious about, then choose a musical form that suits it rather than forcing every animal into the same template.
Putting Sea-Life Songs to Work at Home, in Classrooms and in the Community
For parents, teachers and homeschoolers, the practical question is not whether to play these songs but how to use them. A simple pattern tends to work best. Play the song first with nothing else demanded — just listening, with joining in if the mood takes hold. Then bring in the free accompanying lesson the channel offers on Teachers Pay Teachers, where the same creature can be revisited in a calmer, more focused format. The channel names ESL learners, preschoolers, students with ADHD, late-start readers and homeschoolers among its audience, which is a useful reminder that one song can be used very differently in a preschool circle and in a homeschool lesson.
Homeschooling families often lean on music as a memory hook across subjects, and a short sea-life song slips neatly between longer lessons. Classroom teachers can use one as a transition activity or as an introduction before a nonfiction read-aloud about the ocean. ESL instructors may find the rhyme and repetition handy for vocabulary, since a song gives new words a rhythm to hang on.
The channel’s About page is signed by Queen Angelina, also known as Angela Woodhull, Ph.D., and it invites viewers to send in ideas, thoughts and comments by email — an open door for a teacher who would love to see a particular creature or concept turned into a song. The channel has been building this catalogue since September 2021, and the range is wide: order-of-operations videos sit alongside cabbage, gerbils, pizza parties and a great many ocean animals.
The reach extends beyond the screen as well. The About text notes that the creator is available for live performances at public libraries, schools and nursing homes. Imagine a library story hour built around the shark song, with the octopus and starfish songs following and the accompanying lesson sheets sent home afterwards. The same set could anchor a school assembly or bring a familiar, cheerful tune to a nursing-home audience — which is precisely the intergenerational intention behind the channel’s stated hope that “kids” of all ages will sing along.
