Teenager

Slappy Blackhead is a teenager that in every appearance does things typical to teenage boys.

His character was first used in "D.W.'s Time Trouble" as the title character of Slappy Blackhead's Way Cool Journey Through Time, a movie about a prankster that goes back in time to make his "uncool" principal fall in garbage.

The character was recolored and was made a real person in "Bleep." He was rude to his mother and, after she forbade him to go to a concert, said a curse word to her, which D.W. heard.

He also appeared in "Tales of Grotesquely Grim Bunny" when he went to Meteor Comix when Gerald took it over and sold horror comics at the store. He is friends with another teenage boy.

In the Postcards From Buster episode, "Lost and Found", his mother was seen in Guanajuato, Mexico, which hints he may be from Mexico or maybe Latino American. He may also speak Spanish as well.

In the CGI movie Arthur's Missing Pal, he mowed a lawn near the Sugar Bowl and almost hit Pal because he was listening to music and couldn't hear Pal's barking.
