Diplodicus & Sealion — Free Webcomic for Kids and Grown-Ups

Welcome to the Forest

Sealion and his best pal Diplodicus just want a quiet life — leisurely walks, yummy picnics, and absolutely zero drama. But chaos has a way of finding them when Rabbit and Mole are around.

Diplodicus & Sealion is a free comic series packed with silly schemes, wild inventions, and snack-fuelled adventures. Perfect for kids aged 6+, families, and anyone who loves playful nonsense. New episodes regularly.

Let the mayhem begin!

EP30: Pig-Ment

The forest remains stubbornly black and white following Rabbit's colourful catastrophe. With no obvious solution in sight, help arrives from the most unlikely of sources. Honk Honk's homemade rainbow fizz pop sparkle juice.

It's delicious, it's fizzy, and it does rather repeat on one. Diplodicus hatches a brilliant plan, Sealion delivers a rousing speech, and the forest's restoration gets underway one parp at a time.

About me

Hi, I’m Andy, a graphic designer and illustrator from Surrey, and I make Diplodicus & Sealion.

The comics started as a fun project I made for my kids, who love silly stories and characters. What began as a single mini comic quickly grew into many more, and eventually into this website. I still make them for my kids first — but I’m very glad you’re here too.
