He enjoys dinosaurs and watches Barney. When he made his toy Triceratops bite his toy Brachiosaurus, Alan Grant tries to tell him that they are herbivores and they wouldn't bothered to fight. When Alan shows him a toy Velociraptor and a toy Tyrannosaurus rex and say they love fighting, Ellie tells Alan that Charlie is three-years-old and they should wait until he is five. He alerted Ellie that Dr. Grant needed to be rescued from the river on Site B (albeit unknowingly).
