Penfold

Penfold is Danger Mouse's loyal but perpetually flustered assistant, a small hamster who tags along on missions he'd rather avoid. He fumbles gadgets, panics at the first sign of danger, and greets every catastrophe with a startled "Crikey!" Despite his nerves, he never actually abandons his post beside the world's greatest secret agent.

Terry Scott's fretful, exasperated delivery turns a stock nervous-sidekick role into something genuinely funny, his voice cracking with dread even as Penfold trudges gamely into peril. The writing wisely never lets him become useless; his cowardice is played for laughs, not contempt, so the audience roots for him precisely because he keeps showing up anyway.
