Liam

Liam is a preschooler who made his first appearance in the episode "D.W. All Wet". Liam attends school at the Elwood City Preschool.

He has appeared many times before in past episodes and was used as a background character and didn't speak until the episode The Last King of Lambland, which is the same episode where his name was revealed, even though somebody named Liam signed D.W.'s petition to keep Mary Moo Cow on the air. His name was revealed in the book D.W.'s Guide to Preschool where his name was seen along with a few other names from his classmates.

He is friends with James and is also most likely friends with Emily and D.W. along with the other kids at the preschool although they have not mentioned him before.

He is shown to be kind to others, but not much is known about him, including his general personality.
