The Mosasaurus is a ferocious predator in Jurassic World that mostly has an appetite for sharks. Yet, it will eat other animals such as humans or a Pteranodon that venture into her lagoon. Despite the fact that the Mosasaurus was capable of jumping on to land, she did not seem to actively pursue humans that came close to the tank edges. First introduced in the original 2015 Jurassic World film as a main attraction in the park's lagoon, it famously returns in subsequent films after escaping into the open ocean. This inflatable costume inflates and stays inflated due to the zip up closure. Ensure cuffs are sealed tightly for best air pressure in costume, and adjust the blower fan to point upwards towards the head for best total inflation. This Indominus Rex Jurassic World Inflatable comes with a fan and a dual source battery pack that uses your choice of 4 AA batteries (not included) or a portable charger and USB cord. This inflatable Blue costume fits best on adults 64"-72" tall. The inflated height is approximately 80" tall.. Other Jurassic World, dinosaur and inflatable costumes and accessories (masks, gloves, theatrical makeup...) are sold separately on our page – subject to availability.
