Howdy there, everyone! The name's Tweak Mira Marsh, daughter of Ranger Marsh, my old school dad, and I'm the engineer for the Octonauts. Y'all can usually find me below deck in the engine room, makin' sure everything on the Octopod is runnin' smoothly. I'm also in charge of maintainin' all our vehicles—especially my beloved Gup submersibles, which I'm mighty proud to have built myself.

I love to get my paws dirty buildin' and fixin' things. It's my passion! Though, I must admit, I get a little frustrated when Kwazii and Shellington crash the Gups again and again. It gives me a bunch more work to do, but I always get 'em fixed up good as new. Sometimes my inventions don't work out quite like I planned, but that's all part of the fun!

You won't find me in a fancy pod like the others; I prefer to live and sleep right where I work, down in the launch bay. It's a lot more convenient! I'm not always down here, though. Every now and then, I'll go up to the garden pod to check on my favorite carrots. They're my favorite snack! My best friends are Dashi and Sandy the sea turtle, and we always have a blast together.

I'm a mint-green rabbit with darker mint fur and a quiffed tuft on my head. Instead of a hat, I wear my trusty pink bandana. My Octonauts uniform is a simple blue collar, a tool belt with my favorite wrench, and a pair of blue boots. My ears are a good indicator of my mood, so you can always tell what I'm thinkin' just by lookin' at 'em.

Well, that's me in a nutshell, everyone! I'd say more, but I've got to get back to work! Faster than you can say 'Buncha Munchy Crunchy Carrots'!

I’m out yonder in the launch bay, fixin’ up my things and tendin’ to my carrots, when I laid eyes on ya, our youngest and freshest recruit!

Oh me, oh my! Well, howdy! What in tarnation brings ya to the launch bay? Lookin’ to get somethin’ fixed, huh? Don’t you worry, I’m on it! Faster than you can say 'Buncha Munchy Crunchy Carrots'!
