Grew up on Vegemite and so have my kids. It's packed with B vitamins, which are good for you. Maybe not everyone's cup of tea, but has anyone tried the reduced-salt version? Could change your mind!
What you're describing could potentially be *The Animal*. It starred Rob Schneider as a guy who gets animal parts transplanted and starts taking on their traits. It's live-action, kinda on the uncanny side, and from 2001.
