A late addition to the Bruin Boys, Porkyboy Pig joined the group of mischievous anthropomorphic animal children some time between the group beginning to appear in The Rainbow in 1914 and prior to 1925, as evidenced by his appearance in that Tiger Tim Annual 1925 and inclusion in the Bruin Boys figurines and Bagatelle Game both released that year. Unlike the other Bruin Boys, he apparently didn’t have a twin sister in the Hippo Girls.
Note: Despite the name similarity, he is in no way connected or related to Porky Pig, who debuted at least a decade after Porkyboy.
