Wilfred

Wilfred is the name of Rolf's pig. He mostly appears in episodes that take place on Rolf's Farm. Rolf states that there is a meat ball that stalks Wilfred in the dead of night after Ed tells the story of the "Giant Swedish Meat Ball" that has a "blood curdling scream".

Old Wilfred
Old Wilfred, in the future, has grown to be too fat to move as seen in Take This Ed and Shove it. He has survived for a long amount of time for a pig as domestic pigs usually only live for 10 or 15 years.

Trivia

 * Wilfred sometimes wears Rolf's clothing, as seen in "Truth or Ed".
 * Wilfred is enrolled at Peach Creek Jr. High.
 * He has eaten Rolf's garden hose off screen at one point in the show. Evidence of this is when Rolf hears him squeal (Edd was dressing him up in his father's suit) and Rolf calls out, "Wilfred, have you eaten Rolf's hose again?!?".
 * In Take this Ed and Shove It Wilfred seems to have milk spouts, but is referred to as a boy.
