He is a Grouch
Also Know For Stephen Squirrelsky
- He is also one of Stephen and Andrew's friends.
- Four has green fur all over his body (save for his feet) and is the only monster with green fur and scales (he is the only monster with scales and the only reptilian monster due to his green color). He wears a yellow t-shirt, a dark purple top hat with the number 4 on it, and has dark yellow eyes. He resembles a prehistoric reptile (in particular for having five toes on each foot, he is for some prehistoric reptiles like Ornithosuchus). He appears to be a crocodile-bull hybrid. His voice sound similar to the late Ernest Borgnine, who voices Carface from All Dogs Go to Heaven, and Mermaid Man from SpongeBob Squarepants.
- He is hostile toward all of his siblings except Five. He can sometimes become angry with Five like in "The Mystery of the Missing Five," but he actually loves Five. He likes to pick on his youngest brother Seven by scaring him or just plain annoying him. He also gets into trouble a lot and can get into fights with One and he doesn't really like her that much because of her being bossy. At times, Four can be a bit of a skeptic particularly when it comes to the plans of his brothers Three and Two, and at times he can be a bit of a bully too often teasing and/or playing practical jokes on his siblings.
- Four has a bit of a short temper. Even though he sometimes teases his siblings, he actually cares for all of them.
