Harold Frumpkin

Harold Wayne Frumpkin is a boy in Angelica and Susie's preschool class. He has made a few appearances in the last season of Rugrats and has made several appearances in All Grown Up!. He is voiced by Pat Musick.

Description
Harold has known Angelica and Susie since pre-school, and reminds them of that fact every chance he gets. He is good natured and means well, but Harold can tend to be a bit annoying, to say the least. His social skills have a lot to be desired, and he often matches Phil in terms of grossness, although most of the time he is oblivious as to how gross he is. Despite her constant put-downs, Harold dotes on Angelica, and he may be the only guy out there who worships her the way she wishes everyone would. - All Grown Up! Description from Klasky Csupo.

Looks
In the Rugrats series he is a bit overweight, but loses this trait in ''All Grown Up!. ''He normally wears a green shirt, a pair of dark blue shorts, and light blue sneakers. He has curly, Afro-like, orange hair as well. In the Rugrats spin-off Preschool Daze, he wears the same outfit as worn in the Rugrats series. In All Grown Up!, he wears a blue shirt with brown pants and green sneakers.
