If there was ever a craft that was perfectly designed for kids who love the ocean, this is it. A paper roll octopus made from a single toilet paper roll, some bright blue construction paper, a handful of white dot stickers or paint, and two oversized googly eyes — and what you get in return is one of the most personality-packed little creatures you will ever put on a shelf.
The eight dangling tentacles are what everyone notices first. They curl slightly at the tips, they sway when you pick the octopus up, and they make the whole thing look alive in this wonderfully handmade way. Add the big round eyes and the tiny curved smile and suddenly you have something that looks like it swam straight out of a children’s picture book.
This craft works for ages three and up with adult help on the cutting steps, and kids aged six or seven can handle almost the whole thing independently. It also happens to be one of those crafts that adults enjoy just as much as children do, not that anyone needs to admit that out loud.

A Few Things Worth Knowing Before You Start
The tentacles are cut from the bottom of the roll itself. This is the cleverest part of the whole design. Instead of cutting tentacles separately and gluing them on, you cut slits up from the base of the painted roll to create eight attached tentacle strips. They stay connected at the top and fan out naturally at the bottom. Less gluing, more charm.
Paint first, cut second. Always paint and decorate the full roll before making any tentacle cuts. Trying to paint eight individual strips is a nightmare. Paint the whole roll, let it dry, then cut.
Curl the tentacles for maximum effect. Once the tentacles are cut, wrap each one around a pencil briefly to give it a gentle outward curl at the tip. This small step takes thirty seconds and makes a dramatic difference in how the finished octopus looks.
Step-by-Step Instructions
Step 1 — Paint the Entire Roll
Paint the full exterior of the toilet paper roll in bright ocean blue. Use a wide flat brush and work in smooth even strokes around the circumference. For a richer color, do two thin coats rather than one thick one — the first coat may look a little streaky on cardboard, but the second coat covers beautifully. Stand the roll upright on scrap paper while painting so you can rotate it easily. Let it dry completely.
Step 2 — Add White Dot Decorations
While the blue paint dries or once it is fully dry, add white polka dots all over the roll surface. You can do this with a round foam brush end dipped in white paint, the eraser end of a pencil dipped in paint, or simply use white circular dot stickers. Space them randomly but evenly across the entire surface — dots of slightly different sizes look more natural and charming than perfectly uniform ones. Let dry completely.
Step 3 — Mark the Tentacle Lines
Stand the painted and dotted roll upright. Using a pencil, lightly mark eight evenly spaced vertical lines running from the base of the roll upward about halfway up the roll height. These marks become your cutting guides for the eight tentacles. To space them evenly, start by marking four lines dividing the roll into quarters, then add one mark between each quarter mark — this gives you eight roughly equal sections without needing to measure precisely.
Step 4 — Cut the Eight Tentacles
Using scissors, cut along each pencil line from the base of the roll upward to your halfway mark. Cut slowly and carefully — you want clean straight cuts that stop precisely at the same height all the way around. When all eight cuts are made, gently press the bottom of the roll flat with your palm to fan the tentacle strips outward slightly. They should spread out like a natural octopus skirt around the base.
Step 5 — Curl the Tentacle Tips
Take each tentacle strip one at a time and wrap it gently around a pencil, holding it for a few seconds before releasing. The strip should retain a gentle outward curl at the tip. Work your way around all eight tentacles, curling each one in the same direction for a uniform look, or alternating directions for a more playful wild octopus effect. Either way looks great.
Step 6 — Cut the Eye Backing Circles
From white construction paper, cut two large circles — about 3cm diameter each. These become the white backing for the googly eyes, giving them a larger more dramatic look and making them stand out beautifully against the blue painted surface. Larger eye backing circles make the finished octopus look more expressive and cartoonish in the best possible way.
Step 7 — Attach the Eyes
Using hot glue or strong craft glue, attach the two white backing circles to the upper front of the roll — centered side by side with a small gap between them, positioned in the upper third of the roll above where the tentacle cuts end. Then glue one large googly eye onto the center of each white circle. Press firmly and hold for several seconds. The eyes should look forward or very slightly outward for maximum personality.
Step 8 — Draw the Face Details
Using your fine-tip black marker, draw a small gentle curved smile below and between the two eyes. Keep it simple — a clean arc about 1.5cm wide. Then add two tiny oval or teardrop shapes on each side of the face just below the outer edge of the eyes as rosy cheek marks — you can draw these in blue marker or use a light blue pencil for a softer look. A few tiny dot freckles scattered between the eyes adds extra character if you want it.
Step 9 — Optional — Add a Blue Paper Collar Band
For an extra polished look, cut a narrow strip of slightly darker or lighter blue construction paper and wrap it around the roll just above where the tentacle cuts begin — this creates a clean visual separation between the head and the tentacles and makes the whole octopus look more intentional and finished. Glue it in place with a glue stick, overlapping the ends at the back.
Step 10 — Your Octopus Is Complete
Set it upright, let the tentacles settle into their natural curl, and step back. Eight arms, two enormous eyes, one very satisfied smile. Your paper roll octopus is ready for its ocean adventure — or at minimum, ready for the bathroom shelf where it will make everyone smile every single morning.
Fun Variations to Try
Rainbow octopus: Paint each tentacle a different color of the rainbow using acrylic paint once the cuts are made. Vivid and striking.
Deep sea glow version: Use black paint for the body, neon green or pink dots, and glow-in-the-dark paint on the tentacle tips. Turn the lights off for instant magic.
Pink girl octopus: Hot pink body, purple dots, a tiny paper bow glued between the eyes, and curled tentacles with glitter tips.
Octopus family: Make three in graduating sizes — use a full paper towel roll for the biggest, a toilet paper roll for the medium, and a toilet paper roll cut in half for the baby.
Under the sea scene: Make three or four octopuses in different colors and display them on a blue painted cardboard backdrop with paper seaweed, fish, and bubbles for a full ocean wall display.
Tips for Best Results
Two thin coats of blue paint always beat one thick coat. Thick paint on cardboard takes forever to dry and often buckles the roll slightly. Thin coats dry fast and look smooth.
Cut the tentacles slowly. Rushing this step and cutting unevenly is the one thing that makes the finished octopus look less polished. Take your time, follow the pencil lines, and stop at exactly the same height on every cut.
Store your googly eyes in a small bowl while working — they have a talent for rolling off tables and disappearing forever under furniture.
If a tentacle tears while curling, glue it back together with a tiny dot of glue stick, let it dry for two minutes, then curl more gently. It will be completely invisible once the octopus is standing.
Display and Gift Ideas
A paper roll octopus on a bathroom windowsill next to a small shell or piece of driftwood looks genuinely like intentional home decor. Make it in navy blue or teal for a more sophisticated palette.
For an ocean themed birthday party, set out pre-painted rolls and let children cut and decorate their own octopus to take home. The tentacle curling step is especially satisfying for kids — they will do it over and over.
Make a whole collection in different colors — blue, purple, pink, orange, red — and display them in a cluster on a shelf. Together they look like an art installation. Individually they look like the best craft project you ever tried.
Final Thoughts
Eight tentacles. Two googly eyes. One empty toilet paper roll. That is genuinely all it takes to create something that makes people stop and say “wait, did you make that?”
Yes. Yes you did. And it took less than an hour and cost almost nothing. That is the magic of this craft and why it deserves a permanent spot in your go-to activity list.
Make one today. Then make seven more because you suddenly have a whole collection going. That is completely normal and entirely encouraged.
