Jimmy Neutron

Jimmy Neutron is an American computer animated television series. The series is about a boy named Jimmy Neutron with a monumentally large headwith with an I.Q of 210 which is 10 more than the maximum possible in real life. He goes along with his friends creating wacky inventions that are used for some purpose of him and his family and always go wrong and cause disaster or destruction.

The llama-obsessed Carl Wheezer and Ultra Lord-obsessed Sheen Estevez are Jimmy's mutual friends. They may not be as smart as Jimmy, but they are very loyal to him. They are willing to help Jimmy as much as possible. Normally, these two unlikely heroes play the foils to Jimmy's genius, and sometimes solve the episode's crisis with some innocent or insane observation. Other times, they merely cause the problem. They accompany him in his wild adventures and end up in trouble.
Jimmy's friends also include Cindy and Libby. They constantly tease Jimmy for having a large head and for getting himself and the town into trouble. However, these girls get to join in Jimmy's adventures and help him save the day.

Cindy and Jimmy constantly fight with one another, and consider themselves as "rivals", but eventually, they grow to love each other, leading to a love/hate relationship. In due course, it seems that they fight to hide their true feelings. It is hard to say who really motivates the relationship, but from what we can see, it is Cindy who gives it a little push and Jimmy is quick to respond to these hints of affection. Their relationship develops further in the third season, and in the final episode "Lady Sings the News", Jimmy finally kisses Cindy.
