Open window maniac

The open window maniac is an alter-ego of SpongeBob whose main appearance is in the episode "Hall Monitor". This alias is also featured in the Hall Monitor book and the SpongeBob Saves the Day book.

Description
He wears a dark blue ski mask over his head and a blue hall monitor's uniform with a hat and belt.

History
He appears trying to show two fish the error of leaving their window open through an example.

However, SpongeBob's actions along with his future destruction of the city earn him the label of "the maniac" and make him wanted. Oblivious to his actions and blinded by his hall monitor title, SpongeBob goes after his alter-ego along with Patrick, who is given a poster of the maniac and matches him with SpongeBob.

However, Patrick's low intelligence does not allow him to see they are the same person, so he continuously misinforms SpongeBob that the maniac will attack him as the latter goes with it.

After causing enough destruction, SpongeBob obtains a poster and realizes that he is the maniac. When the police arrive to take him in, Mrs. Puff appears and scolds SpongeBob for his destruction of the city and his foolish actions, much to his sadness.

SpongeBob is not arrested because Mrs. Puff accidentally takes responsibility for his actions. She promises to punish SpongeBob after she is released in six months.
