To ride this mighty animal, you must either feed it meat (3 times, like any other carnivorous animal) so it falls asleep or use a dart gun or tranquilizer gun. When it wakes, it will allow you to choose "Ride". You can also shoot it with a Mind Control Device or use a Cupid Arrow or Bow on it which will also allow you to ride it.
- There are two other objects that are based on the T. rex: the Robosaur, which is a robotic T. rex (and is also more powerful than it) and Edison Yan, a 5th Cell member whose avatar is a martial arts-themed T. rex.
- A Tyrannosaurus is featured on Post 217, which is a famous post in Neogaf where a man named Feep tries out Scribblenauts at a gaming convention.
- It is still inaccurate. Lacks feathers, it's stance looks more like a human stance than a real Tyrannosaur's stance, it's mouth is WAY too big, and it is way too powerful in some situations and way too weak in others.
- Tyrannosaurus appears in Scribblenauts levels: P6-2 and P6-8.
- Tyrannosaurus appears in The Saurus Park.
