Ernie Klump Jr.

Ernie Klump Jr. (Born June 14, 1983) is Ernie's son and Sherman's nephew. He almost never speaks in the franchise (never in the first film aside from burping, choking, and laughing, but seldom in the second). He always laughs when his grandfather farts at the table, even imitating the latter in farting once, much to his grandma's disgust and horror. The only time he speaks is in the second, saying "now that is cool" when his uncle Sherman's hamster grows large from a formula he gave him.

He’s the only Klump not played by Eddie Murphy, being played by Jamal Mixon.
