PRODUCT DETAILS
What's in the Box
- Full-body inflatable octopus costume in purple with hot pink accents — integrated head piece, eight articulated tentacles with suction-cup detailing, and foot covers
- Battery-operated fan with orange housing and ring attachment system — keeps the suit inflated while you wear it
- Does NOT include 4 AA batteries (required for fan operation)
This Adult Inflatable Octopus Costume turns you into a purple sea creature with eight waving tentacles and a giant round head. The inflatable construction gives you dramatic scale — the kind of sight-gag entrance that stops a party. Glossy purple body with hot pink tentacle undersides and embroidered googly eyes deliver full cartoon octopus energy.
Perfect for Halloween, ocean-themed costume parties, comic conventions, stag or hen nights, or any event where you want to be the biggest thing in the room. The battery-powered fan inflates the suit in seconds and keeps it puffed while you move.
Fit & Operation FAQs
How does the inflation system work?
The orange fan unit installs inside the costume via a fabric pocket and secures with a screw-ring from the outside (screwdriver needed for battery pack assembly). Once the 4 AA batteries are loaded and the fan is on, the suit inflates in under a minute. The battery pack clips to your belt or pockets via the attached cord — costume stays inflated as long as the fan runs.
What size should I order?
This suit is designed to fit adults 150–190 cm tall. The inflatable construction gives you flexibility on width — elastic bands at the wrists and ankles keep the fit secure while you're puffed up. If you're over 190 cm, the tentacles may ride shorter than shown.
Care: Wipe clean with a damp cloth after use; deflate and fold for storage. Remove batteries from the fan unit if storing long-term.
