How to Beat T-Rex Boss in Luigi’s Mansion 3

First Phase of T-Rex Boss

When you try to save Toad from the painting, a skeleton of a T-Rex will come to life and will attempt to stop you in your tracks.

Once the fight begins, you’ll notice a bright red glowing spot on the chest of the T-Rex. What you need to do is pick up the giant egg that falls from the ceiling and toss it at the T-Rex’s mouth. Once he’s chewing on it, grab another egg and launch it at the glowing spot to cause some damage.

Second Phase

Now, there will only be one egg for you to use to attack him, meaning that you’ll need to find something else to put in his mouth –this is where Gooigi comes in.

You need to use Gooigi as a distraction and allow the T-Rex to grab him with its mouth. Once Gooigi is being chewed up (he’s fine), now is the time to grab the egg with Luigi and shoot it at the dinosaur’s chest.

Third Phase

Now, try to avoid the attacks of the T-Rex while also luring him towards the exhibits. Once he starts destroying everything, pick up one of the bones and shoot it towards his chest again. You need to do this 3-4 times and then the T-Rex will be defeated.

How to Beat the Caveman – Fourth Phase

Now, once you defeat the T-Rex, the ghost caveman behind the whole operation will pop out of the skeletal remains. This fight shouldn’t be too difficult though.

When he slams his club at the ground, a shockwave will shoot on the ground and you need to jump over it by pressing the back triggers (ZL+ZR) and then stun him with the strobe light. You’ll be able to suck him up now and cause damage. Simply repeat this 2-3 times and he’ll be toast.

Time needed: 5 minutes

To sum up how to beat the T-Rex boss in Luigi’s Mansion 3

  1. Pick up the egg off of the ground and shoot it at its mouth. Then, pick up the second egg and hit it in its chest.

  2. Use Gooigi to distract the T-Rex and allow him to be chewed up by the dinosaur while Luigi shoots the egg at the T-Rex’s chest.

  3. Avoid the T-Rex while also picking up pieces of the broken exhibits to then launch it at the T-Rex. Repeat this 2-3 times.

  4. Now, when the Caveman appears, avoid his shockwave attack by jumping in the air and then using the strobe light on him when he’s down.
