Baby Smitty is a minor character in Monsters, Inc. He is a light blue slug-like monster with four arms, two black dot-like eyes, and a mouth full of razor-sharp teeth. He is evil.

Monsters, Inc.

When he crawls over to Mike Wazowski and says Mike's name, Mike holds his hand out to shoo him away, but Baby Smitty bites his hand, causing Mike to yowl in pain.

He appears in Mike's company play Put That Thing Back Where It Came From or So Help Me, in which he, surprisingly, portrays Boo. He might be the son of Smitty.
