Pokey Oaks Kindergarten is a solely kindergarten school that the Powerpuff Girls attend in Pokey Oaks North. The only teacher there is Ms. Keane whose teaching ranges from basic Kindergarten skills, to laws of advanced Einstein level physics to her students. The City of Clipsville hints in one of its flashbacks that when the girls speed up time and become Valley Girl-ish teenagers , the school may have evolved into a high school.
The students at Pokey Oaks are often seen coloring, playing with toys, or doing simple math problems and/or sums.
