If LocoNuts lost about a hundred pounds he'd be a dead ringer.
I think that extra 7 stone is what makes The Locust perfect for that role. After all, if you're gonna have somebody in a species of pajama intended for infants, The Locust's extra baby-fat fill's 'em out better than the scrawny, more adult looking, obviously faking it Pajama-boy currently being run in the ad campaign.
I'm sorry, but PajamaBoy just doesn't sell "suckling at the teat of the Nanny State" the way I think The Locust could.
