Tufty sees an ice cream truck and goes out with his mummy to get a cone. Meanwhile, an unescorted Willy Weasel gets a cone but is run over crossing the street. Miraculously, the weasel survives. Tufty says always cross the street with your mummy. Tufty makes it very clear that if you don't do things his way, you'll be hurt, terribly.
Ice cream represents our humanity.
Here, it precedes pain. Thus, we are encouraged to turn to the skwerl-side. In the film, Tufty follows his mummy to the ice cream truck. Our experts agree that Mummy represents an impenetrable barrier. Thus, Tufty is stating that resistance to skwerl world domination is futile.
