Ziploc gives a twist to the traditional back-to-school ad with a campaign in which the "kids" are actually played by animals.

A series of spots entitled "Little Beasts," by Energy BBDO, show adults playing the teachers and parents, while "beasts" like llamas, monkeys and goats play the students. They cover three different scenarios: picture day, the first day of kindergarten, and in this spot (arguably the funniest), parents being called to the principal's office. All the ads carry the endling: "Kids are a trip. Pack accordingly." RSA's Rob Cohen was the director.
