I am Fan. I wanted to know if anyone else are fans Kitten - Boo.
I am!! Boo and Sulley are really cute.
Sion Reason You All Very Cute On Boo 
Boo is my favorite character in the movie!
I may not be a fan of small children, nor of Sully as a character, but even I have to admit that Sully and Boo’s relationship is very special and is portrayed really beautifully in Monsters, Inc. The arc that Sully has to go through, slowly but surely realising that Boo and, as an extention, all human children, are not harmful is handled really well and by the end it’s pretty gut-wrenching stuff. By far the best relationship in the film, and I’d say it’s generally one of Pixar’s best relationships between two characters.
I absolutely adore Boo so much. She’s simply adorable and very crucial to the plot. If it wasn’t for her, Sully and Mike’s perspective towards humans would have never changed.
Is that the relationship with Boo and Sulley is very well explained, I am a fan but it’s so nice when you say kitten
