Big M “Wombat Shark”, “Trunk Call” & “Dinosaur” [00:30]# “Things start to get interesting with Big M” these commercials show us. In the first one, an Australian wombat, a small bearlike creature that fancies dressing up as a shark, starts attacking his master, who’s just drinking Big M – by sucking his toes. The second commercial takes the term “trunk call” literally, and in the final one 3-D TV really lives up to its promise of getting the action right into your living-room.
