Leo

Kids in the animated class have a variety of skin tones and a mixture of family issues, but race, culture, and religion don't play significant roles. Their problems seem intended to feel broad enough to be applicable to children from a diversity of backgrounds. A bullying child is said to act out of insecurity. One girl feels relief when she's told she's not so special after all. Another says her family doesn't understand her because she's smart and into science. Another talks too much and learns to stop and ask questions of other people. Boys learn to accept the changes that come with puberty.

Animated characters, especially animals, face some peril and injury. Animals recall being "abused" by children -- hit, thrown in hot water or into the air, and cut into pieces. A lizard's tail is sucked up by a vacuum and cut off (it grows back, he says). A teacher nearly falls out of a moving bus, and a child nearly crashes a full school bus he's driving because he's too small to hit the brakes fully. A man is hit by a car and is fine. Kids threaten to "destroy" a substitute teacher, planning to throw gummies at her and change their names on her. A teacher throws metal stars like a ninja, and she has a fight with an alligator. Kids deal with loss, grief, and anxiety. Parents also have fears and try to protect their kids from any dangers or difficulties.

A boy doesn't know where babies come from and says he thought they came out of his mother's "butt." A turtle confuses the matter by explaining to him how turtles lay eggs in the sand. The animals make suggestive jokes, like when Leo tries to climb into Squirtle's shell, and the turtle says he would have liked dinner first. A drone has a crush on a turtle and gives him a heart-shaped gift. The turtle takes off his shell and is in a jockstrap; we see the turtle's bottom. (We also see him pee in another scene.) Boys face puberty changes, like body hair and changing voices.

"Suck," "butt," "pee," "tush," "brat," "dork," "stupid," "weirdo," "doo doo," "headcase," "motormouth," "snotty," "booger," "shut up," "jeez," "Oh my God."

A child mentions a rumor about a kid smoking in middle school. A teacher calls another substitute a "closet drunk."
