Origin
Bluey was an Australian lad who had defended himself from a Great White Shark while out surfing and discovered to his shock that it had false teeth. The shark sought revenge for Bluey stealing the dentures, rendering “Gums” safe, and so began a constant contest between the boy and shark, as Gums would regain his teeth and try to eat Bluey, only for the boy to steal them once again and seek to keep the teeth forever out of Gums’ reach.
Creation
Bluey was created by Robert Nixon for Monster Fun #35, and continued to appear on and off through to the entire run of Gums’ strip.
