The Utahraptor's appearance scared Mum away from her nest. Sonic and Tails first thought he was a robot created by Robotnik, but then assumed he was a tyrannosaurus before they clearly saw the fierce Utahraptor. With the creature soon coming towards them, Sonic and Tails climbed up a tree to avoid it. Afterwards, the creature lumbered towards the lake. Soon after, Tails gave a long, piercing whistle to it and it headed towards the heroes, where the Utahraptor was successfully distracted towards Robotnik's robots by Sonic and Tails as they ran.
- The Utahraptor is based on the real-life dinosaur species. Unlike the real-ones, which were about the size of humans, however, the Utahraptor in Sonic the Hedgehog in the Fourth Dimension is much larger.
