Have you ever heard of Dashi Dog or Tunip the Vegimal? Unless you have a small child obsessed with The Octonauts, you probably haven’t. But, if you are like I was and you have a child that is obsessed with The Octonauts, you know that finding a Dashi Dog or Tunip the Vegimal Halloween costume isn’t going to happen. You are going to have to make one yourself.

DIY HALLOWEEN COSTUME: THE OCTONAUTS DASHI DOG
Well, here is how you do it.
STEP ONE: GATHER YOUR SUPPLIES
First, put together the basic pieces that you can turn into a costume.
- Brown shirt – I found a brown shirt in the closet.
- Pink skirt – I ordered a pink skirt online.
- Blue boots – We splurged and bought blue Uggs that she wore all the time.
- Blue tights – We found some tights at Target.
- Camera – We used our Fisher-Price pink camera.
STEP TWO: LOGOS
Second, print out some Octonauts logos on iron-on paper after you search for Octonauts images and find what you want. I printed directly onto the iron-on paper that I ordered online right on my home printer. Next, I ironed on a large Octonauts logo on the back of the shirt and a small logo on the front. You can shop this post below for printable iron on sheets.
STEP THREE: DASHI NAME TAG
Third, make an embroidered name tag for the front of the shirt. I just cut out an oval of felt and embroidered “Dashi” on to the felt and then sewed that on to the shirt.
STEP FOUR: COLLAR
Fourth, make a blue felt collar and sew it onto the shirt. As you can see in my pictures, I just cut out the collar from the medium blue felt, sewed on some little arrows from the dark blue felt, and sewed the white trim all the way around the collar.
STEP FIVE: THE SKIRT & THE TAIL
Next, sew a border or trim on the skirt. I also added the little flower at the top of the skirt by just wrapping around the trim in a spiral pattern and then sewing it on the skit by hand.

Don’t forget to make a puppy dog tail out of felt and sew it onto the back of the skirt. I stuffed this one with a little poly-fill.

STEP SIX: THE HAT
Of course, Dashi will need a hat. So, here I used a felt bowl that I found at Michaels and I covered it with blue felt. Next, I cut out a logo from white felt and sewed it onto a circle of medium blue felt and sewed the logo on by hand. I also added the rim around the hat and sewed the medium blue stripe around the rim.



STEP SEVEN: THE AIR TANKS
Finally, make air tanks out of a pool noodle and duck tape. I cut up a pool noodle to be the air tanks and I made the straps to hold it together with some pink polk-a-dot duck tape I found at Target.



STEP EIGHT: TUNIP THE VEGIMAL
To make a little Tunip the Vegimal costume for my son, I just dressed him in an orange shirt and made a hat out of a felt bowl. I cut out green leaves from felt and sewed them on the hat/bowl. I used the stiff felt for this.












Now that you’ve got the costume picked out, here’s a fun idea about how to pour paint on pumpkins that you can see here.



Most of the supplies I used for these costumes came from Michaels. The pool noodle came from Target.



Just load these sheets in to your laser printer and print your logo.



This is a felt bowl. I used two of these and turned them into the hats you see.



This is Creatology felt from Michaels and the color is Peacock. This was the accent color for Dashi’s hat and the base color for the collar.



This is Creatology felt from Michaels and the color is Baby Blue. This was the base color for Dashi’s hat.



This is Creatology felt from Michaels and the color is Brilliant Blue. This was the accent color on Dashi’s collar.



This is Creatology felt from Michaels and the color is White. This was part of the logo on Dashi’s hat.



This is Creatology felt from Michaels and the color is Goldenron. This was what I used to make Dashi’s tail.



This is polyester rope trim and I used it around the bottom of the skirt, around the collar, and to make a flower at the top of the skirt.



My pool noodle came from Target.



Michaels has a ton of printed Duck Tape to choose from. This is what I used to hold Dashi’s air tanks together and to make the should straps for the air tanks.



This is stiff felt that I used on the top of Tunips’s hat.
