It is a monster that inhabits Monstropolis, just like all other existing monsters. He is more than two meters tall and has blue hair with purple spots, and he is the one who holds the record for scaring children. He lives quietly with his best friend Mike Wazowski, until one day, while searching for some reports from Mike, Sulley discovers that one of the doors to the human world was left open. As he approaches to close it, he discovers that a girl has entered Monstropolis, and this is harmful to all monsters (since they believe that children are toxic and that is why they fear them). Mike and Sulley hide Boo (that's what they call her because when Sulley found her from her he scared him with a Boo!) While they look for her door, to take her back to the world of humans. But none of this is easy, since Randall, Sulley's rival, annoys him in everything he does and tries to harm him. Throughout the whole adventure, Boo takes a lot of affection for Sulley, even though she is a monster. help me summarize this please ... It's for my brother's homework, he's sick and may lose the year
