Compsognathus Compsognathus ( komp - sog - NAY - thus ) is a small dinosaur appearing in LEGO Jurassic World . Background . " Compsognathus " is one of the 20 playable dinosaurs in " LEGO Jurassic World " . In the game , it possesses the unique ability to enter special pipes called Compy tubes thanks to its small size and is the smallest dinosaur in the game . " Compsognathus " also appear as common enemy dinosaurs which often attack the in groups . Packs of " Compsognathus " also appear as obstacles that prevent access to certain objects , areas , or Workers In Peril ( characters the player can rescue to earn a Gold Brick ) . These packs do not attack , as their mere presence is enough to frighten the player control characters from getting close . The only way to drive these packs away from the area is to use Eric Kirby ' s unique " T . rex Scent " ability to throw a flask of " T . rex " urine that will drive away the " Compsognathus " allowing the player to whatever the pack was guarding . Unlike " The Lost World film " , Cathy Bowman ' s tragic encounter with the " Compsognathus " does not occur in the game as the Bowman family encounter a " T . rex " during their visit to Isla Sorna instead which Deirdre Bowman feeds a hotdog while the family takes picture with it . In the area of the Hunter ' s Campsite on Isla Sorna , the player can rescue Dieter Stark from a pack of " Compsognathus " by driving them away with Eric Kirby ' s " T . rex Scent " ability allowing Stark to be unlocked for Free Play and to obtain a Gold Brick . Before being rescued while screaming for help , Dieter Stark will call Robert Burke an idiot for his erroneous assertion that " Compsognathus " weren ' t dangerous . Like Dieter Stark , two other Workers In Peril can be rescued from Compy packs on Isla Sorna ' s Hunting Plains and Isla Nublar ' s Tour Route Exit using Eric Kirby ' s ability to drive them away . In the " Breeding Facility " level , a Compy can be found swimming in one of specimen tanks that Billy Brennan can take a photograph of along three others ( a baby " Velociraptor " , fish , and teddy bear ) in order to earn a Minikit . Two " Compsognathus " are also playable in the " Velociraptor Escape " bonus chase level where they run through the Breeding Facility to escape the " Velociraptors " along with Alan Grant , Paul Kirby , and Udesky . " Compsognathus " also appear as minor enemies in the " Spinosaurus Showdown " level attacking Grant , Amanda Kirby , and Eric as they assist Paul Kirby in the showdown with the " Spinosaurus " . One of the " Compsognathus " standing next to Grant , watching the Spinosaurs ' defeat only for Grant to humorously order it to heel causing the Compy to sit down . In the " Parking Garage " level of Jurassic World , Gray Mitchell and Zach Mitchell find a sick " Compsognathus " in the abandoned Visitor Center ' s abandoned parking garage . After healing it by feeding it a candy bar , popsicle , and some meat the thankful " Compsognathus " will befriend the pair causing it to become a playable character for the rest of the level and assists the Mitchell brothers in fixing one of the old Jurassic Park Responder jeeps . After the jeep is fixed and as the boys are driving out of the garage , the " Compsognathus " will step on the button of garage door controls to keep to garage door open preventing door from closing on the boys as they drive out of the garage . It will then wave goodbye to the boys as they drive off , then jump off the door switch and leave as the surviving Robert Muldoon , Dennis Nedry , and Donald Gennaro ( who in the game survived the events of " Jurassic Park " but are left stranded on the island ) peek out from a broken down jeep they where hiding out in . Three " Compsognathus " skeletons also appear perched on top of the Jurassic World ' s Main Street fountain . " Compsognathus " can be unlocked by obtaining its Amber Brick in the " Mobile Lab " level . To obtain the Amber Brick , after the Eddie Carr uses his truck wench to stabilize the front car of the Fleetwood RV Mobile Lab , the Amber Brick on top of the front car can be reached via climbing the hand holds on the side . A Compys ' Skeleton alternate skin can also be unlocked by collecting all 10 Minikits in the " InGen Arrival " level ( " Camp Sabotage " & " Mobile Lab " ) , which will also unlock the " Compsognathus " hologram in the Innovation Center in Jurassic World on Isla Nublar . Like all the dinosaurs in the game , a custom " Compsognathus " can be customized via the Dino Customizers in both the Visitor Center and Innovation Center . Using certain parts of other dinosaurs can grant the player ' s custom " Compsognathus " with certain abilities ( such as the " T . rex " head option will give the Custom Compy a LEGO Amber destroying roar ) in addition to its own unique ability to use Compy tubes .
