This Adult Inflatable Tanystropheus Dinosaur Costume brings the hilariously long-necked prehistoric creature to life at your next Halloween party, costume event, or stag do. The battery-powered fan keeps the blue-grey dinosaur body inflated while you see out through the chest opening — your face becomes part of the gag. Standout feature is the exaggerated neck stretching up to the open-mouthed head with painted yellow eyes and rows of white teeth.

Perfect for Halloween parties, costume nights, novelty events, stag parties, or any occasion where you want to make an entrance as a prehistoric comedy act. The Tanystropheus species is famous for its absurdly long neck — this costume delivers that visual punch in full inflatable glory.

FAQs

How long does the battery last?

Requires 4 AA batteries (not included). Most customers report 3-4 hours of continuous inflation on fresh batteries, which covers a typical party or event. Bring spare batteries if you're planning a marathon night.

Can I sit down while wearing this?

You can, but the inflated bulk makes it awkward. Most wearers find it easier to stay standing or lean against a wall. The costume deflates quickly if you need to take a break — just switch off the fan, wait 30 seconds, then re-inflate when you're ready to rejoin the action.

Care: Wipe clean with damp cloth; do not machine wash. Store deflated in a cool, dry place away from sharp objects.
