How to Play Monsters, Inc.
Quick start
Choose New Game and enter the first available door from the hub. Read its requirement screen, then guide Sulley through the stage to collect the required pieces of Boo's door. Avoid CDA agents, hold B with the D-pad to creep past danger, use R to roar and push movable objects to open the route. After a cleared stage, place the recovered pieces into Boo's door puzzle; completing that puzzle unlocks the area boss.
