If your Halloween goal is to turn heads at every party you attend this year, we found just the costume for you — and thanks to an Amazon Prime Day lightning deal, you’ll be able to snag it for 75% off if you’re quick.

So, what’s the costume, you ask?

Glad you asked! Meet the Jurassic World T-Rex Inflatable Costume, because why dress up like a human from the world of Jurassic Park when you can be a dino instead?

Right now, you can get this costume for 75% off — just $27.99 — while the Prime Day lightning deal is in effect. Once all of those have been claimed, it’ll go up to 57% off, which is still a whole lot less than the $110 list price.

This one-size-fits-most costume has a battery-operated fan inside that inflates the suit into the towering figure of a T-Rex. Of course, you’ll need some AA batteries for that — and isn’t it so convenient that a multipack of AA batteries is also on sale for Prime Day? Coincidence?

At the time of publication, 21% of available lightning deals have been claimed, so there’s still time for you to get an inflatable costume for yourself.
