Halloween Family Costume 2018: Finding Nemo (again), Jellyfish, and Daddy Shark Do Doo Do Do Doo

I posted our Finding Nemo Halloween family costume 5 years ago when my older daughter was Nemo, I was a sea anemone, and my husband was a scuba diver.  Well, fast forward to this year, and now my younger daughter fits the Nemo costume, so we had to revisit this aquatic theme again since the Nemo costume is so cute.


It was perfect because I actually just got a new Synergy wetsuit for an upcoming triathlon, so I found our original US Divers snorkel set and remade the scuba diving backpack and accessories for my part of the costume.  Here is my original post on how to make a scuba costume.

For my older daughter, we made a jellyfish costume that I thought turned out so wonderful that I don’t want to take it apart now that Halloween is actually over!  I am thinking of hanging it on the ceiling in their bedroom!


So because I am too busy and overscheduled, of course this all got put together the day before Halloween.  Actually, the EVENING before Halloween.  We went to the Halloween store first to see if we could just buy a Dory costume for my daughter, and a shark or turtle for my husband.  But we couldn’t find anything.  So at 6:30pm, we drove to Michaels and bought:


  • A large sheet of turquoise felt or fabric 36×36 (if needed)
  • 2 large googly eyes (optional)
  • 2 different loop yarns of varying turquoise colors
  • Turquoise duct tape
  • That’s it!  We already had a kids umbrella at home, so we didn’t need to buy one.  If you need an umbrella, I really like this blue clear umbrella so that you could skip step one altogether!


1. Cover the umbrella with turquoise felt or fabric (if needed).

Measure the umbrella and make sure the fabric is large enough to cover all the surface area.  36×36 was perfect for my kids’ umbrella.  I cut a little hole in the center for the tip of the umbrella to poke through.


My daughter and I used the turquoise duct tape to secure the four corners of the felt first.  Then we taped the sides until no fabric was loose or hanging.


Nobody sees the inside, so don’t worry about making it pretty.  But do use lots of tape!


2. Make the jellyfish eyes (also optional).

So actually, jellyfish don’t really have eyes like we do.  Except for the box jellyfish which has 24 eyes, but 2 of them kind of look like ours.  My daughter wanted eyes, so… we put eyes on!  Originally I was going to buy white felt and black felt, and make large eyes, but then we saw these perfectly matching googly eyes and decided to get them.  They are 4 inches tall.


3. Make the tentacles.  

This is the most important part of the costume in my opinion!  We looked through thin yarn, thick yarn, wooly yarn, all sorts of yarn, and finally found these looped yarns, which had the most dimension and “waviness.”  It was the perfect choice!  You really have to see and feel the different varieties to see what you like.  My daughter chose these because she said they were so soft.


My daughter is 48 inches tall so I measured and cut the tentacles to be about 36 inches so that they wouldn’t drag on the floor.  Then my daughter used the duct tape to tape them all around the umbrella.   We used 24 strands of tentacles.  The remaining pieces of yarn we made into a necklace for my daughter to wear with tentacles hanging down.


That’s it!!!  Here she is during the school parade.  LOVE this jellyfish costume so much!!! Now can you imagine it hanging from the ceiling in their bedroom?  I think it would be such a fun decoration!


OK… so 3 out of 4 costumes done.  Dada’s turn!  Da-ddy Shark Do DOO Do Do DOO…. “Dada can you be a nice shark?” asks my little one, AKA Nemo.  Ok Nemo, ok.  He won’t eat you, but he will eat your candy.


1. White Belly

My husband approved of this costume, because, well, he got to wear sweats and a hoodie.  Which is what he would have worn trick-or-treating anyways.  So why not just “decorate” his hoodie???  I found one of his old grey hoodies and had to cover up the USC logo in the front.  Perfect, because a shark needs a white belly!  I only had 8.5×11 white felt, so I used 2 sheets to cover up the logo, but ideally if you have a larger sheet of felt, one sheet would be better.


Just round out the corners so there is a vertical oval on the belly.  Since everything I make is usually temporary, I stick with duct tape versus sewing or gluing.  Temporary.  It works!


2. Shark Mouth

I found a thicker white felt sheet that was stiff versus flimsy, and it happened to have shimmer.  I cut a large zig zag line across the center (vertically).  These are the shark teeth, one on each side of the hoodie.


I took the duct tape and taped on the even ends to the inside of the hoodie.  Nothing pretty.  Just securing the teeth as much as possible!


Next, I cut one red felt sheet in half vertically and rolled up duct tape to stick the red lining on the inside of the hoodie (covering up most of the duct tape I used to stick the white teeth down).  I like the red accent to make it really look like the inside of a mouth!


3. Final Touches

I saved 2 thin strips of red felt and cut them into thirds.  I rolled up duct tape to stick the red felt onto the sides of the hoodie to make it look like shark gills.  I used 3 on each side.


Then I used a pair of googly eyes at the top sides of the hoodie.


Finally, I made the fin with a thick black foam sheet.  I couldn’t think of anything else but using duct tape to hold the fin in place.


So hard to take a selfie and capture the entire shark!!!  But you get the idea!  Now let’s put all our costumes together!


Happy Halloween!!!
