Your wish has been granted in the form of: wearable dinosaur costumes!
I've seen these sorts of costumes in live performances of Walking with Dinosaurs, and in various other street-art shenanigans, but it had never occurred to me that you could just buy one for yourself! These magnificent beasts are available via Only Dinosaurs. They don't mention the price of each model, only that it is dependant on the number ordered. Read - probably very expensive.

You can back the campaign and receive your miniature not-so-terrifying-more-cutesy model for around ~$20 USD plus shipping. Or if you can't wait, you can download the 3ft KitRex pattern for free!
