A Concerned Kiddo

In the flip of a mermaid tail, you knew. You knew your baby needed to be Disney’s Sebastian for your family Halloween costume. Not because they’re crabby. Not even because their older sibling had already claimed Ariel as their own. It wasn’t even because you had your heart set on Ursula which left just a couple fish or Triton to choose from. No, it’s because your babbling baby naturally channels Sebastian's style. That undeniable urge to share all their adorable sputters and coos about good music, having unsafe numbers of shiny things on display, and how to raise kids “right” while being ignored. Because how often does anyone really listen to Sebastian?

Design & Details

Get your pint-sized performer ready for their Halloween debut with this exclusive Disney Sebastian Baby Costume from Disney’s The Little Mermaid. The officially licensed ensemble starts your baby’s transformation from squish to crustacean with a dynamic bodysuit. Light red and orange Minky materials build Sebastian’s soft upper body and belly while bright red foam shapes the sculpted sleeves, flip-top claw mittens, and four additional attached legs. Snap tape along the inseam make getting the body suit on and secured quick and easy. A detachable shell keeps dressing your baby simple as well and makes pairing down the ensemble fuss-free. Included leggings and foam booties promise to keep little legs warmer and looking just like Sebastian’s while rounding out the Made By Us costume!
