'Harry Pitt is a rather unkempt boy whose appearance is similar to "Pig-Pen" from the Peanuts comics and a classmate to Blossom, Bubbles, and Buttercup in Pokey Oaks Kindergarten. He is also one of the major characters of the Cootie Gras's storyline.
Harry scared the children because they were afraid of "cooties" which also caused the girls to avoid him. However, Mojo Jojo noticed this and used Harry as a way to scare the PPG from crime. Harry ends up kissing Blossom, which makes the girls realize that cooties aren't real. This causes the girls to develop a crush on Harry, who ends up getting covered in red lipstick marks courtesy of the girls.
Although he was used for evil intentions, Harry himself didn't appear to be evil at all, rather just a boy looking for someone to return affection to him and to not be afraid. Also, Harry didn't appear to be terrorizing off the Girls intentionally; he didn't even have to try nor did he have to say anything at all, be it menacing or reasoning. One could say that Harry was a living kryptonite to the Girls before they realized cooties were not real if he could defeat them so easily with unintentionally scaring them.
- His name is a pun on the term "hairy pits".
- Unlike most of the kids at Pokey Oaks Kindergarten, Harry has gone through the most voice actors, ranging from Tom Kenny, Dee Bradley Baker, and E.G. Daily.
- He is one of the few characters to be kissed by the girls, and the only one to be kissed by them at the same time.
- Out of the girls, he has a fixation on Blossom, as he targets her when they are trapped in the pit with him, and she is the only one he ends up kissing. Ironically, Blossom seems to be the one who kissed him the most when she and her sisters corner him.
